I read an article in BYPoultry about forcing broodiness in a hen by enclosing her in a little box on top of some eggs/golfballs, then covering the box in black fabric. I tried this yesterday, and my hen was already broody by this morning. She already seemed interested in brooding, and I wanted her to get going with the whole business. She's an EE sitting on 5 of her own eggs, and 2 teeny little d'uccle eggs. woohoo!
