I foster baby desert tortoises ranging from just a couple weeks old to a year old. I have 18. 10 Texas deserts and 8 California deserts. I have noticed my California deserts are not eating and a few staying in their hides. Well last night and this morning I lost 3 babies. 2 at a month old 1 at 1.5 months old. My day temp is 86-87 basking 93-95, night 81-83, humidity lowest 65% mostly kept around 75%. I have megaray mvb as their basking and Arcadia dual 6500/12% uva/uvb bulbs, che for their night heat. Are their bodies just naturally set to hibernate no matter what the temps are? I thought if the temps were warm enough they wouldn’t. What can I do for these babies so I don’t lose any more. These guys seem so fragile compared to what my Leo babies were. Thanks for your input.
