Well, at least thats what it looks like. My barred rock has had a lump growing on each toe for the past year or so, and it has progressively gotten bigger. It is covered in scales like the rest of the foot and is hard so i know its not filled with puss or anything like a wort. On the underside of both feet where the lump is, there is a clump of hardened dirt. I tried taking it off but It almost seems like it is attached. Like I said, this has been going on for a really long time and its is not bothering her, but still, anyone have any ideas as to what this is.
