Broody Hen Trouble

So I noticed my "bonnie girl" was not getting out of the nest. Next day, same situation. Broody hens sit on the nest and refuse to get up. They got it in there head that they are sitting on eggs to hatch them. They will not eat or drink. I have read up and there is a few things to do to "break" them.
When I tried to pick her up off the nest and she puffed up, pecked and even growled some. Real mean for sure. I read one cure is to dunk them in cold water which is supposed to shock them and cool them off. I am not to keen on that method. Another method is to put them in a cage with food, water and no bedding material. The idea is to "cool" them off. Some folks even put a fan on them to cool them off. I guess their body temperature is higher during this time. Some people say that after a couple of days they snap out of the trance they go into.

Here she is all settled down and not moving.

Look how she puffs up and is giving me the mean eye.

I had to wear gloves because she was pecking me so hard. I took her out and put her in the outside pen. Gave her food and water. She had not eaten I bet for a few days. It is a cooler day and there is a light mist of rain. That should help to cool her down and hopefully break this broody attitude.
