Hi friends! I wanted to ask for some advise about one of my RR's. She lost most of her neck and wing feathers about 2 months ago and I had to separate her from the rest of the flock because they were picking on her so badly. I noticed that her comb and waddle got grayish and shriveled up a bit. Is this just a bad mult for her or could if be something else? She has been eating and drinking fine but concerned about the cold weather ahead. How long does it take for a chicken to regrow their feathers back after a mult? I have a heat lamp on in the coop at night for when the temperature drops. Any suggestions are much appreciated.
