Will broodyness spread?

I have a broody BO right now, too. Yesterday I tried just removing her from the nest when I caught her sitting. Moved her about 5 times to no avail. This morning I put an igloo cold pack under her. She sat on it for 10 min., so I went ahead and moved her to the run so she could eat. Then I caught another hen sitting on the cold pack, so I took it out and put it back in the freezer. As soon as there is an egg in that box, broody will likely be back in there trying to hatch it. She's determined, I'll give her that. The first time she puffed and raised hackles at me, I was truly scared, but she is a sweet chicken so I've been able to handle her without getting pecked or scratched. If the cold packs don't do the trick, she'll be isolated tomorrow. I really hope the others don't start in.
