I've had my 5 hens for a year now, only one of them is broody, she sits in the nesting box all day long. I havent seen her get out at all. The other hens go about their business, when i go to gather the eggs, she growls at me and tries to peck me. I can still get the eggs, and I dont mind, but is it OK for her to sit all day long. Should I try to get her out or just leave her alone? She's been doing this for several weeks now. When do they stop?
