We have a 5 mo. old Polish/Black Star cross (Blue ) who's been limping for the better part of 2 weeks now. We've checked her leg and foot and the only thing we find is one scale that's a bit lifted right above her foot. No bugs or anything on her or anyone else in the flock. I did give her a dose of Arnica yesterday which seemed to help but she's still limping. Could anybody have any ideas? She hasn't fallen or anything else we can think of. Thanks in advance!!
