I bought her from an auction...I do not know how old she is. She might weigh a couple of pounds. I came out to my garage this morning (where she was kept last night) and she is barely hanging on. I have her laying on a blanket now and I have found there is a brownish black round hard spot on the bottom of one of her feet and the entire leg is sensitive. I have not had chickens long enough to know what this could be and could this be causing her problem?
It sounds like she is very sick. Is there any chance you could take her to a vet? The brownish spot on the bottom of the foot, combined with leg sensitivity, could be a sign of infection. Did you notice her limping before this?
