Like the title reads I have a Cochin that I am not sure how old she is. The last few days she has been lethargic, falling over, drooling a little from her mouth and her belly is bare and she has some scabs on it. We brought her in tonight and put her in a warm dark place in hopes she lives. I have eleven other chickens in the pen with her and they all seem to be fine. Does anyone have any advice?
