So for the past few days my 1 year old female bearded dragon has been covered in stress marks and her colour has been a lot darker than normal. Her UVB needs changing this month. And her basking temp was around 105-110 (could that be too hot for her). I noticed she wasn't basking as much, so I dropped the temp to around 100
Sure, changing the UVB would likely help out when you get a chance.
What type of thermometer do you use, a digital probe or temp gun?
Is she eating much right now?
She won't eat much veg, and she will only eat around 10 large locusts. I think she may be going into brumation. I've noticed her spending less time basking. And she's been under her log all day when usually she is on top of it basking
