We have two silkies that started over the last 2 months. The weather has turned cooler and the last two days they have stayed in their respective "egg laying" corners. One of them is actually sitting on a plastic easter egg. She pecks and makes noises when you try to get anything from under her. I don't think that she realizes that my wife slipped the real one out earlier. This is our first try at chickens and we are not sure, but does weather change cause broodiness?
