I have a Dutch bantam that is insanely broody. I mean really, I have never seen a chicken wanting to hatch as bad as her. She is working on her fourth hatch now. When she finishes with a set of chicks, she lays eight or nine teeny white eggs and then insists on hatching again. She actually broke the skin on my hand once when I attempted to take some eggs. After about two weeks I give up and let her hatch. I am going to try the wire cage method as soon as she's finished with these three (she's so tiny that most she can hatch is four!).
