Lacy, the nests are only significantly illuminated for a few hours a day right now around 3-4PM because of the angle of the coop and the nests. Also the nests are in the back of the coop, of course, and the coop itself isn't exactly sunny inside most of the time... One BIG window, facing south and a little bit west with a few trees to the east of it and a 6' fence 15' away... It's kinda gloomy in there most of the time, though the girls always know when it's time to get up bright and early every day. I can't build in something like a door like that. I'm not spending crazy money or lots of effort on dysfunctional birds; it's not practical. I won't spend $100 changing around my coop to keep two birds I can replace for $8 each and bribing someone to take me out to get replacements with a tray of cupcakes & a dozen eggs or something. I *can* try putting something up like a board across the front of the nests to make it a little darker in them, but considering these guys were waiting in the nest on the roost bar, stalking the other hens as they come in to lay their eggs I am not sure that would help!
I feel kinda like my best bet is trying to take them out of the group and re-introduce them one at a time, forcing them in as strangers to become the lowest ranking hen in the group after they spend some time in a cage like a broody buster where they may lay an egg but it sure won't stay in the cage! Maybe I can even strap one "fake egg in so they always have something hard and painful to peck at. That way when they come back all they will have is sore beaks and every hen with flog them for coming near the nests during laying time. Plus they won't be a team any more. It MIGHT just work.
If I can find someone willing to trade me their egg laying hens for rabbits or rabbit meat I will just say "forget it" and replace them.
