I'm not sure which chickens are doing it, but at least 2 are laying from the roost. Half the time they break, which obviously drives me nuts. Is there any way to get them to start using the box like the others? I have Wyandottes, NH Reds, Barred Rocks, and an Easter Egger. It's obviously not the EE. The rest of the other eggs are light brown and dark brown. It's only the dark brown eggs, but I'm still not sure which hens are laying them. All the birds are the same age (almost 6 months) and have recently begun laying.
