My broody and her two chicks are still sleeping in the nest box, and it is making for a mess! I think she wants to take them to roost, but the other hens are pecking the chicks on the roost, so she takes them back in the box. The chicks are just over four weeks old, and are ready to roost, but the big girls aren't making it easy for them. They don't mess with the chicks during the day, but night is a different story. Honestly, there isn't enough room on the roost for all seven of them. While they physically fit, it is pretty tight quarters. The coop was designed originally for four-five birds, but I could maybe add another roost in a pinch. A smaller coop isn't that big of a deal here. I live in Florida, and the girls are never inside unless they are sleeping or laying their eggs, but I don't want to be cramming them into a tiny house. I do have plans to make a larger coop soon, I have a wooden playhouse that I'm going to convert as soon as I can get it to my house from my friends place. I guess I will just have to deal with a dirty nest box until then, because I don't think she will take them to roost with the older hens picking on them.
