So my beardie has has a crooked tail from the time i got him, but he was taken care of some one before me. I'd read a crooked tail ment calcium defficancy, but no way to fix it but didnt bother them, but now iv read its a symptom of mbd and lately he's been kind of lazy. When i put crickets in his cage he hardly goes after them. So can you plz tell me what a crooked tail means and what the syptoms of mbd are please.
