But yesterday we put in 2 partitions that divides the shelf into 4 separate little cubicles for the hens to lay. They are now MUCH happier. Before, all the hens wanted to lay on the ends, next to the walls. They seemed to like that best. But because they all wanted the same spot, they'd fight over the spots.
Every spot now has a wall on each side.
It is kind of like a cage and it is extremely well ventalated therefore keeping the hens body heat quite cool. If you put the broody in there for a few days that should work. If you want to get her to stop you could just block off her cubicle and make all the other cubicles look as different as possilb from the oone your broody is in. That is how i get my silkie to stop setting. We used our broody coop to introduce pullets into the laying house about six weeks ago.
