I have a hen I just noticed limping today, she wasn't limping yesterday that I could tell. Upon inspection I noticed what I think is hopefully just a puncture wound but took pictures to post on here to get some opinions. I'd like to catch it early if it is something like bumblefoot. I really don't want to have to remove her from the flock for treatment if possible, but I realize this being on the bottom of her foot I may have no choice since there is no way to keep it clean. Also I don't want to have to give the entire flock antibiotics in their water just to treat her. Any advice or insight would be much appreciated!
