Hello, my brother found what seems to be a broiler breed, or a cornish X in Coney Island, NY, wandering around on the street. He took her home because I have chickens and he thought that I would be able to take her in. She looks very weak and lethargic, all the feathers are missing from her back side and some from her belly. She doesn't seem to be injured. She stands in one place and closes her eyes, occasionally will peck at food and water. I currently have layers and don't have experience with a meat bird. I read they usually do not live very long, not sure what to do with this poor girl. We are going to give her some worm medication and she doesn't seem to have mites, but I think it would be too traumatizing to try to introduce her to my flock. Any advice welcome.
