2 days ago, we noticed that our 1 1/2 yr old beardie started limping. I can't tell for sure whether it's the front or back legs, but I think it's the front. He is still digging but not walking much.
He eats, but it's difficult for him to catch the crickets because he can't move fast enough to get them.
We have not taken him out of his cage lately, so I know he couldn't have fallen to hurt himself. Could a deficiency of Vitamin D3 or the lack of UBV lights be the cause of this?
Also, other than greens and crickets, what else would be good for him to eat to get the proper nutrition he needs?
Thank you for any help you can provide.
