I have a Brahma hen thats gone broody in an upper nest box. When the chicks hatch they will have to jump to get to the floor of the coop which has a good layer of shaving on it, but They won't be able to get back into the box with mama when she brings them back inside, I hope to move her when she goes into lock down but not sure when that will be, is it 2 or 3 day before hatch date? I think if I move her then she will stay with the eggs and not go back to the upper nest, anyone ever done this and can give some tips?Or should I wait till they hatch then move her?
