I have bearded dragons that require specific lighting to properly metabolize Calcium and Vit. D. Lizards raised in captivity ,especially juveniles that do not have access to proper lighting will develop Metabolic Bone Disease. I've heard people mention exposure to the sun helps with cross beak. As I currently have a little cross beak chick, I'm considering adding a source of uva/uvb to the brooder. Any thoughts on this?
