My production red has not been using her left leg for about 3 days. I have inspected it, and can't find any visible injuries or differences between her good leg and her bad one. Her feces appears normal, and I don't see any other abnormal symptoms on her. She is about 1 1/2 years old and is molting, so has not been laying lately. I currently have her in a crate by herself. She has been eating and drinking, although she mostly eats sunflower seeds and fruit scraps rather than the layer ration. I thought maybe she had injured her leg or foot somehow, but she has not shown any improvement. I currently have 12 free range hens, five 2 month old pullets, and no roosters. The pullets are in their own coop and run. I also have a labrador, but she is very good with the chickens and has never hurt them. I am at a loss as to what I should do to help the injured chicken, so any suggestions would be much appreciated.
