I have a 6 month old salmon faverolle who had been laying for only a month. She has been glued to the nest for the past 3 days. No eggs are under her. She pancakes, puffs, and growls when I poke under her. When I take her off the nest, she fluffs the bedding in the coop around her. I kick her out to the run, but I always find her back in the same nest. She is not pulling chest feathers like a broody would. Her abdomen feels normal and she doesnt seem sick. Probably broody?? I have never had one go broody so young, and in the fall.
