Hello all. I have 19 chickens, 17 of which are pullets and 2 are cockerels. Over the past few weeks, I have seen a Buff Orpington cockerel act like some of the pullets. I have observed him cackling with some of the pullets, and imitate laying an egg, liking getting into a nesting box, making a nest out of wood shavings, and sitting there for ~5 minutes; afterwards he gets out (without laying an egg), and walks off like nothing out of the norm happened. On I have also seen a pullets sound a warning call when an eagle was seen, but that was on one occasion. So, is it normal for one gender of chicken to act like the other?
