I got these ladies from rural king a couple days ago, and lost one last night. They said they are 10 weeks and when I don't have a lamp on they bunch up, but if it's on they spread. I read in one of the forums that the bunching means they are cold to turn on the lamp and if they are spread out they are ok, unless panting which is too hot. So I have been turning it on at night, and off during the day. The temps here are in the 78+ to upper 80s during the day and has been in the upper 50s at night and expected to climb. Is it warm enough to stop using the lamp or to hot already? I don't want too loose another so soon!
