I have a dark cornish who has been sitting on the nest for almost 3 weeks now. The other hens just lay in the other boxes, and usually if I take the eggs out from under her she moves to get on any other eggs, but really no egg stays there long, I take them as soon as I can after being laid. Will she naturally get 'un-broody'? Just wondering what to expect...I know she has hatched eggs before as when I got her she had chicks with her. Any thoughts?
