I have a 10 month old Buff Orp pullet that has tricked me twice into thinking that she is broody. But then at night, she gets out of the nest and goes and roosts with the other birds. When I am gathering the eggs, she is on the nest, and puffs up at me, squawks loudly, and pecks at my hands. Is she thinking about being broody, or is she just laying an egg and being over protective about it? If any of my other hens are on the nest while I am gathering eggs, they make a couple of nervous clucks and that's it. They sometimes leave the nest and wait for me to move on to the next nest before coming back. But they never puff up at me, squawk bloody-murder, or peck at me. I would love for her to go broody full-time, what can I do to encourage that?
