I went to pick up my BP tonight and I've noticed it's belly is a bit dry and flaky the best I can describe it. This is my first BP and I've only had it 3 weeks. It shed 2 weeks ago in one piece. It's eating fine weighs 230g been feeding weaned rat's every week. The temps are 86 on the hot 80 on cool side basking spot is at 91 from uth. And humidity stays between 52-58%. Is this normal for the belly to feel a bit dry. Thanks in advance.
