Outdoor tortoise enclosure Version 2.0!!!

Our outdoor tortoise enclosure expansion is finally ready to be shown off to you! I started the expansion project last August, and then had to take a break during the cold, wet winter months. As soon as it was warm and dry enough to work outside, I was out there! Before showing you the work-in-progress, I thought I'd first show you the finished product: 

Tadaaa! Outdoor tortoise enclosure expansion!
The above picture shows the large portion of the enclosure in the shade - I took the pic in the morning. That side of the house gets full afternoon and evening sun!

So, let's rewind to last August. Here is the tortoise yard Version 1.0 - not bad, actually... nice sun, nice shade, good weeds to eat... the tortoises were happy.

The 'old' enclosure... Version 1.0
However, I wanted to be able to section off the males from each other and from the females, and wanted to provide MORE room for everyone. I also wanted the enclosure to be attractive and functional. We have the space, and so I went for it.

First, I wanted to make sure that I actually did things 'right' this time - pre-planning, measuring, etc... rather than winging it as I worked. I used a free online landscaping planner to come up with the following design plan:
'The plan' 
Next, I measured, staked, and used spraypaint to mark where I needed to dig. The lines were going to be straight, darn it! Once the lines were marked, I started removing the grass. The grass wouldn't hurt the tortoises, but I needed to dig the anti-escape-trench, and Russian tortoises don't particularly like to eat grass, so it can take over.
Starting to remove the grass where the expansion will go
I had to find a good option to drain the gutters in a way that wouldn't flood the tortoise yard... we get a lot of rain in the Spring and Fall! You'll see the solution I came up with in later pics. I also had to dig up a bunch of toxic plants from the South side of what would be the tortoise yard.

To prevent the tortoises from digging out, I dug a deep trench. This was back-breaking work... I used a prospecting axe, and dug and dug and dug. When the trench was done, I installed a line of pavers/bricks, embedded deeply enough that the tortoises wouldn't tunnel out.

I had to work bit by bit, digging the trench and removing the grass. This is what it looked like when that portion of the prep-work was done.

The digging and grass removal is done!
After this point, winter came, and it became too cold and wet to continue. Life also got really busy, so I had to put the expansion project on hold until this Spring. As soon as it was warm enough, I got back to work. First, my friend Lynne and I took down the structure of the old enclosure (THANK YOU!). Then we started laying the foundation for the new wooden boundaries. Unlike in Version 1.0, the Tortoise Yard 2.0 has a leveled foundation - extra work, but VERY worth it in the end. I first put landscape fabric into the trench, and then a leveled layer of gravel. Then I installed lawn edging pavers (which I got for free via a neighbor who was going to bring them to the dump) into the trench. Then we installed the 2"x10" cedar boards, using rebar to hold them upright. Cedar is harmful to reptiles. However, these boards had weathered for 1 year, and so don't pose a danger to the tortoises outdoors. You can see the work in progress in the following picture:

Lynne decided to be camera shy, so I didn't get a picture of her working... I did manage to catch our shadows on camera together though! We spent several crisp winter days working out there together.

Once the cedar board boundary walls were all installed and the rebar was hammered in and attached to the boards to hold them in place, the really hard part of the work was finished. The pre-measuring and pre-planning paid off: the boards were level, I had the right amount of lumber, and it looked nice.

Far from done, but it gives a good idea of the space
However, the work was not yet done. The tortoises could potentially climb over the 10" boundary, and the kids (and various other critters) could certainly climb/walk/jump into the tortoise enclosure. (Ps: see the drain pipe that I installed, through a hole in the board?). I started to install the railing, with hardware cloth (similar to chicken wire, but smaller holes).

Installing the railing
Installing the hardware cloth was a 2-person job. I managed to install about 15ft of it myself, using my hands, feet, and head to hold things in place. NOT efficient. Thankfully, I was able to enlist my hubby and Lynne to help me (Thank you, again!). I used little stainless screws and washers to hold the hardware cloth onto the wood - this worked MUCH better than the staples I used in Version 1.0!

If you look in the next picture, you'll see that in addition to the anti-dig-mote (filled with lawn edging pavers), I also placed 12x12 cement pavers all along the inside edge of the tortoise yard. The soil is flush with the edge of the pavers, and so tortoises will walk up and down, but won't be able to dig at the edge. With the many other digging options I've provided, I don't anticipate any escapes.

Functional, but not quite as pretty as I'd like...yet.
The vertical 2x2 posts and the hardware cloth were enough to functionally keep tortoises in and kids out, but since we will see the tortoise yard daily, I wanted to make the structure more optically pleasing. To do so, I installed a 1x2 railing, with a 1x4 railing top, complete with miter cut corners.

...working on making a proper railing...
I reused railing pieces from Version 1.0, so I had to piece them together a little bit... but in the end, it worked out nicely. To add to the anti-escape factor, I installed the railing with an inward-facing lip, just in case a tortoise happened to manage to climb up the hardware cloth.

The structure is finished!
Since my kids sometimes help me feed and water the tortoises, I even installed a little 'short person entrance' - the rest of the fence is purposefully the perfect height for me to step over without much effort.
On the far left is our leopard tortoise's pen, with the big 'juvenile tortoise' bin (converted koi pond). Then the large Russian tortoise area, with the sectioned-off areas to keep the males separate from each other and the females. We named their sections "Dukelandia" and "Rozlandia" (the males are named Duke and Roz).

At this point in late January, the weather was warm enough some days that I could even let the tortoises spend a few hours in their outdoor space.

Here are a few pics of the inside of the enclosure, before plants started growing in properly. I seeded out two broadleaf seed mixes (from Carolina Pet Supply and from Tortoise Supply), and also transplanted hundreds of weeds I dug up in other people's yards (#crazytortoiseladywantsyourweeds).

 I tried to make the interior of the tortoise yard interesting to explore, with different textures such as little hills, rock piles, rocky flat areas, soil, planted areas, and logs to climb over or hide under. I placed sight barriers to help the tortoises not become too territorial towards each other. I also made a weird little log tepee, since tortoises like to bask in filtered shade.

The leopard tortoise area (below) has some grass in it, since this species does like to graze. The large black koi pond will have the juvenile Marginated tortoises in it. I will create a separate post showing more of the leopard tortoise area at a later point.

You can see part of the leopard tortoise area here.
One part of the tortoise yard expansion I am particularly pleased with is the old fire pit that I re-purposed into a baby tortoise enclosure. First, I asked my hubby to drill some drain holes into the bottom. Then I filled it with dirt, and planted a little garden inside with stones, moss, a soaking dish, and plenty of yummy weeds. The mesh cover has holes large enough to let UVB light in, while protecting the babies from predators. The adult tortoises can easily walk under the structure.

It will still take a few more weeks for the weeds I planted to start growing in properly. Soon, the whole area will be lush and green! Here are a few more pictures that I took today, a few weeks after the above pictures were taken. The weather has been beautiful (65-70 degrees air temp, warmer on the ground), and the tortoises got to explore their new habitat.
Spring is here!

Some of the weeds I transplanted... 
This year I am keeping the males separate, to give the females a break. The females may still lay fertile eggs, as they can store sperm for years... but at least they will not be bothered. Here is a view of Rozlandia, with Roz climbing one of the logs I put in there for him. The fern is deer fern. The tortoises ignore it.

It was cute to see that Roz knew EXACTLY where the sun would hit first. He positioned himself just right on the log to catch the first rays!
Ready for when the sun hits Rozlandia
It is always fun to watch tortoises explore and claim their 'favorite' spot to make a wallow or burrow. Lady likes to burrow down halfway near a plant, and then lazily lies in the sun, nibbling on leaves close-be.

Duke didn't settle down in Dukelandia for a while. He spent most of the day walking around.

Here is a view of the area the female Russian tortoises live in. It is shaded in the morning, but around 10:30am, the sun creeps in. I brought the tortoises outside when there was enough sun for them to bask in.
Do you see the tortoise who found the sun?
Mila did her best impression of being a rock. Well, a weed-eating rock... there was a blooming dandelion plant there a few minutes ago!
Why yes, that is the most comfy way to eat.
I checked on the tortoises sequentially throughout the day... and they were happily exploring and munching away.

Can you believe that Mila is almost as large as Timmy now?! She is growing up! She laid a single fertile egg last year, which hatched in October.

Here is a view of the tortoise yard, as seen from balancing on one of the posts:

Can you spot the tortoise?
 ...and here is another view from ground level:
How many tortoises do you see?

I would say, the verdict is overall: Our Tortoise Yard Version 2.0 is tortoise approved!

Jill has a green mustache from eating weeds...
Was it worth the hard work? Absolutely! Guess what... instead of paying to go to the gym... you could build your tortoises an outdoor enclosure, and get a workout in the process!

Ps: The tortoise yard expansion plan includes a cold frame, which I will show in a separate post. Many of the shrubs are already in place, and I used reclaimed materials when possible. I want tortoise owners to know that it is possible to build a beautiful and functional enclosure on a budget. You may have to comb Craigslist for free materials... but in the end, it is worth it! Grand total material cost was $185, which included lumber, hardware cloth, and high quality screws. The bricks/pavers and some of the lumber was reclaimed. I could have done it for less, but chose the 'pretty' variety for some things (e.g. getting very large continuous pieces of lumber, and building a 'pretty' railing, rather than leaving things rustic).

Egg season has begun!

Today Timmy girl decided it was time to lay the first clutch of eggs this year. I have suspected that she was gravid, since she was pacing a lot, eating tons, and had scarfed down 1.5 entire cuttlefish bones within a few days.
After 2 weeks of beautiful sunny weather, unfortunately it is cold and rainy again, so putting Timmy outdoors to lay her eggs was not an option. Thankfully, my marvelous Timmy girl is ok with laying eggs indoors into a deep bin filled with warm, soft, moist soil.
When my son observed Timmy digging with her back legs, I set up such a bin near the basking area, with a little ramp up to it, and she knew exactly what it was intended for. Within a few minutes, she started to dig her nest hole!

After about 1.5 hours of digging, Timmy started to drop her eggs. She caught each egg with one leg as it came out of her vent. I happened to catch it on my phone camera:
You can see the egg starting to come out of her tail. 

Once the egg was out, Timmy gently moved it into further the hole with her foot

Next egg is on its way out

Timmy uses her foot to catch the egg, so it doesn't fall into the hole and break

Third egg is out. 
Within a few minutes of each other, Timmy laid 3 beautiful little eggs, weighing 20g, 22g, and 22g. These are a little bit smaller than last year's eggs, but still a very normal size. I will incubate them at 89 degrees F for the next 65-75 days.

All tucked in for incubation
When nesting, tortoises go into sort of a trance, and they must be allowed to finish the whole process, from digging a hole, to laying the eggs, to covering up the hole. If they are interrupted (e.g. if they are removed after laying eggs, without being allowed to cover the hole), females have been known to be in a serious funk for many months. This has never happened here, because I make sure that the nesting female does not get interrupted. If I catch the tortoise in the act of laying, I carefully remove each egg from the hole as it is laid, and replace it with a round egg-sized rock. That way the eggs aren't in danger of being crushed. The female doesn't care, and happily covers up the rocks, pats the dirt to firm it down, and walks away.

After laying her eggs, Timmy's legs were super wobbly, but she headed down the ramp, basked for a little while, and then tucked into some fresh weeds I offered her.

You can see that she completely covered her nest hole in the bin before leaving.

Nothing like a good meal after birthing those eggs!
It has been 22 days since I woke Timmy girl up from brumation, and she has not been with a male since last year. However, tortoise females can store viable sperm for many years. If these eggs are fertile, they are due to hatch near the end of May. Last year, Timmy laid a second clutch about 3 weeks after the first clutch, so I am curious to see if this happens the same way this year.
