What does a hen act like when it becomes broody? I think I may have one that is doing it. She sits in the nest box all day, and when you try and lift the lid to the nest box or tough her she screams at ya. When she comes out of the nest she makes weird noises, and puffs her body up, and struts around almost like a turkey. This is a buff rock, and I only have hens no rooster. Thank that's whats going on here? eta: this chicken just started laying maybe 3 weeks ago.
