I've searched the forum and found links to the problem of roosting in the nest boxes, but I have the opposite problem: the first egg from my 21 week old flock was laid while the hen was sitting on the roost. It fell 2 feet and smashed on the poop board below. I'd noticed her creating a nest in a corner of the coop for a couple of days and saw her sitting in it a couple of times. I was sure she'd lay there. But no. (I also have four nest boxes, which is where I'd like them to lay of course, but at this point I'll settle for "anywhere on the ground"!) Today I bought two fake eggs and put them in one nest box. Any other suggestions? Will they keep laying on the roost once they've started?
