My chickens are settling in nicely and they have all learned to lay eggs in the nesting box. However, one of them likes to sleep in there, as evidenced by a lot of

in it. There is also a nest hog, who causes the "alpha bitch" chicken to cackle at the top of her voice, screaming b. murder if she cannot get in there! At dusk, the night before last, I caught the perp and evicted her. I removed the box, put in some fresh bedding and returned it the next morning. Three of them laid their eggs in the corner of the coop, and one didn't lay an egg
Last night I turned the box around to face the wall, and allowed them to use it again first thing. Four eggs from four chickens! Yeah!
My question is, how long do I have to deny access to the box for the penny to drop?
