I have a cochin/australorp mutt that went broody on me early this winter. I figured it was the fake eggs I left in the nest boxes for "training". I removed the fake eggs and just kept tossing her into the snow until she got over it, in about 3 weeks. Then, someone ate an egg, so I put the fake eggs back in again to stop the egg eating. After two weeks of that, she went broody again. Now I started to wonder. I wanted to see if it would happen again. More than a month passed without any broodies, and the fake eggs went back in. Well, after about two weeks, she went broody again today! I left her three EE eggs to hatch for me. Would she have gone broody without the fake eggs, or can she be that easy to "stimulate"?
