I have only had one broody hen since I've owned chickens and she's been broody twice. The first time I didn't even own a rooster. The second time, the rooster hadn't gotten it right yet, so hers were not fertile. I put a couple of eggs from another hen under her so I wouldn't have to break her up and she hatched them in May.
I store the eggs in a safest manner possible till shipping. I suppose if I had hens that had broody tendencies and knew their eggs were fertile, I could allow them to stay in the nest. I just haven't had broodies except one Buff Orp.
wooden pony, I haven't even hatched any Blue Orp chicks and with egg orders for weeks on end, I may not unless I hatch some over the winter, LOL. I do mail out their eggs, however.
