Why are you moving them? It sounds like they have a great system setup. I would just leave them where they are and let them co hatch this brood.
My Silky Topsy had her daughter Vanilla Ice pop into the nest with her to help hatch her last brood. It's completely normal. And then after they hatched the two co mommaed them. Topsy quit at four weeks, but Vanilla stayed with them until nine weeks.
If you must move them/her I'd first determine which is truly broody and which is a wanna be. My guess is the night sitter is the broody. Once she stops laying its pretty certain to be her. Then move her at night. I make sure there's hardly any light and cover her head with a towel for added darkness. Then put the eggs under her once she's in place. It's better to wait until you are sure she will stay in the new nest to give her the real eggs. But in your case, just give them to her by putting them under her one at a time. She will settle in on them for the night.
Here are Topsy (black) and Vanilla Ice (white) in the nest box with their newly hatched chicks.
And here's a front picture of that nest box area![]()
I really wish I could. and this comes at the worst time. My flock of Brahmas sold to a guy coming to get them monday. I have told him im keeping the broody until she hatches the chicks. But I cant keep both broodys.
This kind of sucks.
But thank you for the information guys!
