I think I finally have a broody. One of my BO girls has been in the nest box all day, and whenever I go in there she puffs up and growls at me. I bought BO's and silkies hoping to get a broody so I can hatch some eggs, and I'm hoping she decided she didn't want to be left out on mother's day and now she wants to be a momma. How long should I wait to make sure she is broody before I get eggs to put under her? I don't have a rooster so she is sitting on a couple of golf balls and I think there are a few unfertilized eggs under her, she won't let me get close enough to check.
