My broody girls Ruby and Betty are driving me nuts. It has been over 3 weeks now and they continue to stay hot. Ive done broody jail which they definately object to especially Betty. She gets very frustrated in there. I lock them out of the chicken house every day so they can not go inside and brood in the straw. They have a free run of the whole garden. They eat and they drink and they brood . Will this broodiness go away by itself in time and is it normal for them to remain broody for long periods sometimes?
