My box turtles bedding, Eco Earth coconut fiber substrate, keeps getting lodged in front of his back legs. When he walks, he just packs more and more in the hole. I used to have moss and cypress mulch mixed in with the Eco Earth, but I took it out because it was contributing to the compaction in his leg holes and I thought pieces of the mulch might be poky and painful when they get stuck in the cavity. I thought that would help, but the Eco Earth alone is still getting lodged in there. I am able to remove it with soaks and tweezers (very carefully!), but I have to remove in constantly or else it keeps building into a massive clump! Is there another substrate I should be using so this does not happen? His leg hole is quite large so I fear that whatever I use will get in there and that something like wood chips would just be more painful to have lodged in there. Is this even a big issue if the coconut substrate gets stuck in there? Thanks in advance!
