I have 3 laying hens and 1 very old rooster who have the run of our fenced backyard during the day. One of the hens just got done (about a week ago) with her second round of broodiness in a few months. For the last 2 days she has been scratching and hiding in the back of a cat carrier that is on our porch and squawking loudly for an hour or so at a time. The rooster joins in with the squawking and they make quite the racket. She is a bit skinny and has some thinner patches of feathers from the brooding but otherwise looks healthy. Could she be in pain or just being a weird chicken?
