This morning I went out early to look in the henhouse, and one of the barred rocks was in there, making little growly noises in the nest box. There was an egg under her, and she kept standing up, and nudging it under her with her beak, then settling down on it again. When I reached under her to get the egg, she got a little agitated. And that what they mean by going broody? That she wanted to set on that egg, even though it wasn;t fertilized?
