I would like to present a question here about a first time Silkie broody. She and 2 other first time broodies, hatched chicks together just a couple of days ago. There is one pullet that, for a reason unknown by me, seems to get agitated and will start running around chasing and pecking the chicks, hard. It looks like the Keystone cops, all these chicks running around and this hen whacking them. I don't know why she does it or what sets her off. Once she settles down, she will allow chicks under her. So far, she has not injured one. This pullet did hatch in a different nestbox from the other 2 pullets but they all sit together and "pool" the chicks. They are in a coop with other chickens but are separated where nothing bothers them. Does anyone have ideas or experiences with this aggression? I would appreciate advice or ideas.
Thank you.
