A little over a week ago I posted about one of my chickens having lost her feathers and seemed skiddish around me and the other chickens. She has been around us all her life and never had any problems with us. She was also lifting her foot a lot. We checked her for bumble foot and separated her from the rest of the flock. She was doing better, growing her feathers back and putting weight back on her foot. So two nights ago we put her back with the other girls. Today we noticed that she has blood on her back where her tail feathers start. I'm worried about what is happening in that coop! Should I be, or not? I feel like I need to find a new home for this poor girl! I feel bad for her!
