I rescued a baby gray world two weeks ago, and my guess is he's around eight weeks old now. He seems to be thriving and growing, but recently he appeared to have a scab on what I assumed was his testicle, but i've been reading that they don't have testicles at this age. The scab, it's gone, and there's a a tiny little hole that's like an open wound. He definitely seemed to be biting at it a lot for a couple days. So maybe he just created the whole, but I don't know what else to do. And he's dragging his back end around like it's irritating him. It's it a tumor? What do I do?
