We were given a bearded dragon. I think she is at least 2-3 yrs old. They only feed her crickets and only 7 a day. We got her a uvb light and when she is under it she turned black. I have no idea if this is normal or not. I am doing research and she has calcium sand under tank heater heat rock. Should I keep all these or not? She is now eating like 30 crickets a day and we are giving her veggies. She is active now. Just wanted to introduce and welcome any and all help ps reptiles give me the creeps but she was so mistreated so I told the kids they could have her lol
