One of my hens lost a toenail and has been limping on that leg all spring. The problem is she is mean, she actually will grab my glove and hang on and shake her head. Even if I get her from behind she turns around and bites, growels, hisses, cackles, you name it. She will even flap her wings and twist out of my hands. I can't catch her unless she's in her box. I can tell she's in pain but she's not going to let me treat her. Any suggestions. I can't tell why she lost her nail or if it broke off. It looks a little swollen but doesn't look infected.
