I have six Isa Brown hens who started laying two to three weeks ago. Four of them lay in the nest box, one on the floor randomly, and one while sitting on the roost. However they all lay standing up. In the nest boxes they hunch over because there is no room to stand up so the eggs are fine. The one who lays on the floor(my little rebel) will sit down for ten minutes, get up, walk around and drop an egg wherever she is which always breaks the egg even though it lands on hay/straw. The sixth hen, I don't think she knows that she is laying an egg because she lays them from the roost which is two feet off the ground(of course shattering them) and wlks away as if everything is hunkydory. So my question is how do I keep the two odd hens from breaking the eggs when they lay?
