my hen is broody in the hens' favorite nesting box and i haven't gotten an egg from any of the other hens since she's been broody. when she get's off the nest for her 10 min. break, it's usually when i'm not home and i think the other hens are laying in the same nest box that she's in and then she lays on them to try and hatch them. i already have 4 eggs under her that i don't want to get crowded out or smashed. but how do i get her off without hurting her or the eggs? any info would be helpful.
