Before I invested any more money trying to make this setup work,I'd invest in a Reptobator. Good proportional unit. I have 4 running right now.They have been in continuous use for the last three years and I have had great hatch rates with them.
A lot like a housecat in some ways,but he still has a pretty wide wild streak.Unusual habits,almost doglike. He'll play fetch for as long as you want to. Walks on a leash like a dog.Very affectionate and playful.
I just righted an old male redfoot who was on his back in the enclosure,about 5 minutes ago.. I actually lost one of my best breeders last summer due to being upside down in the hot sun. I'm assuming another one is turning them over,as there is nothing for them to climb on.
