Hello Folks, Very new to raising chickens, so don't know why some my chickens are picking feathers from the neck of other chickens. It's cold in the winter, so hate to see one of these bared neck get sick for cold. These birds are RIR hens, about a little over a year old, not laying at the moment. Why is this behavior and what can do to prevent from further happening? We are new to raising chickens and don't know much yet. So any and all info would be much appreciated. Thank you in advance.
