My bearded dragon appears to be shedding or brumating or both. It’s winter time here and he’s retreated to his cave for multiple days, stays awake and eats when tong fed but doesn’t wanna come out. His arms are white and some of his bearded. Hasn’t pooped in over a week maybe 2 weeks. Today I pulled him out of his hide and set him on his rock to bask and get some UVB anyone tell me what’s wrong ? After pulling him out to set him on basking spot noticed he didn’t really wanna use his left arm which is the mostly white limb
