I have just noticed that one of my hens, Holly, has what looks like a large, pointy growth on the back of each leg? It's about half way up the leg so it doesn't touch the ground, she has four toes on each foot... so it's not a toe, I'm really worried, it looks horrible! I have never noticed it before, but I can't say for definite that she has never had it because I just don't know, this will teach my to be more observant I guess. She was a commercial hen before I adopted her from a rescue society if that makes a difference? Please help though I'm worried about her!
