Hello all. So I recently have built a enclosure in my backyard. It's still not finished but it's getting closer. I will have 4 Cherryhead Tortoises in there. All for are about 6 inches down their carapace. I live in Va so it gets cold in the winter and hot and humid during the summer. I'll keep them indoors during the winter months. So my question is, what can I use to lay over a 3rd or half the enclosure so it's not totally in the sun. Also currently I have a grass bottom but I have about 15 bags of Cypress Mulch I was planning on spreading in the enclosure. Should I spread it totally or should I maybe spread part of it and leave the rest grass? Any other suggestions you may have is more than welcome. I do have more plants to plant I just have not had the time to plant them yet. It's my first real building experience so it's definitely not perfect. And again I still have a bit more work to do. I wanted to build an enclosure so they'll be outside more along with it being predator proof.
