You don’t have to take her off the nest, she’ll do it by herself just fine, as needed.
Do the others try to bother her in the nest? Or is she able to keep it to herself? When you get the eggs, mark them, so you’ll be sure which are the ones you want to hatch. In case anyone else sneaks an egg in there, remove it.
I have separated new moms with their chicks right after hatching and given them their own ‘apartment’ for a while. But if she is high enough in the pecking order, maybe she’ll protect them just fine. Whether the others bother them or not just depends.
Youll have to make sure your area is ‘baby proof’ by having waterer they can’t drown in, feeder they can access etc.
I have a broody that I am allowing to stay w flock. She’s pretty high in the pecking order, so I think it will work out. She’s on day 11.
Good luck! Keep us updated!
