My daughter rescued a stray hen from a cat near her school. Limping on left leg. Comb bloody. Missing feathers on head, back, rump. Other feathers were cut by someone, probably previous owner. She did not have any bathroom debris for 8 hrs. Eating, drinking and using potty now. I made a cozy home in my shower for her. For 1 day, very little movement. I have 11 pullets and 1 cockerel. I took new girl outside. Now that she had seen my flock, she's become a chatty Cathy. Excited to limp around on leg and eat near my flock. I kept at a distance because of her bugs. I don't know how to treat them. She stinks too. I will probably need to treat my flock too. Any advise?
