I have two pullets that have gone broody. My Marans went first and after 3 weeks she stopped. Then my Ameraucana went broody soon after. Now my Marans is trying to sit on the nest again! I Don't have a rooster, and I don't want anymore chickens at this time. My question is why are they going broody like this? I am trying to let my Ameraucana finish up and discourage my Marans from doing it at all this time. But this is so frustrating! Do they copy each other?
