I just went out to feed the girls this morning and my Rhode island red that is molting was acting really odd. I have actually never had a bird molt in the few years I have owned chickens, so I'm not sure if their behavior changes. That being said, I noticed her crouching her body down, holding her neck parallel with her body, and taking steps backwards. Her feet are also swollen and red between her toes. It has also been below freezing for several nights in a row. She is eating and drinking and foraging still.
