One of my two pekins bills looks like it is peeling. I think it might have gotten torn up on the wire on their cage I lock them in at night. She will try and climb the wall when I go to let them out in the morning. I don't know if thats what its from or not though and if it will be okay to leave. Its like a thin sliver of bill got shaved off and is just flapped back over where it was before. No blood or anything and its about and inch and a half long and 1/4-1/2 inch wide. Should I clip off this piece like I would dead skin tissue? Or just leave it and it will fall off eventually. They play in the water and it doesn't seem to float around or anything stays stuck to the bill where it should be but when I touch it I can freely pull it down. I'll try and get a picture of it tommorrow if I can get some help.
