I had 2 hens that were broody one right after another in November and December -- it was getting cold here and we worried about them alone in the wire cage on the porch without anyone to snuggle with, but it didn't take long to break them. Just 3 - 4 days. We did cover the cage overnight, though with a blanket; and one night when it was going into the single digits we put the poor little thing in the back cellar way which is cool, but not freezing. They were very happy to be back with their friends after that. It did take a couple of weeks for them to restart laying again.
Good luck!
and yes put food and water in the cage. Someone had suggested mushier food, which is a good idea, because when they drop the pellets, they drop out of the cage and the poor bird is looking for "where did it go?"
