Have u switched the UVB light?? It needs replacing every 6Mnths the best and most recommended is the Reptisun 10.0 T5. They can’t eat, or move and have no energy without UVB and proper heat. Here’s a photo. U can order online on Amazon or a specialty pet store. For heat get the zoomed CLEAR basking bulb never ever use colored or coiled bulbs.Hi, her beard has been normal coloured, I've never seen it go dark so far. I have been giving her vegetable slurry every day since she's been off her live food which she eats well and also keeps her hydrated. So far she's still hiding away and off her food but she did seem slightly more interested yesterday and licked a locust. Thank you will let you know when I have seen the vet.
