I also have a broody. I put mine in a wire cage, it's not important the type of wire but the bottom should be wire or something she won't try to "set" on. I use a dog kennel and take out the bottom tray. Normal feed and water for three days. No less. After 3 days let her out at night and put her on the roost. I have 21 hens that are boody's at all times of the year. Some are lousy mothers so I break them all the time.
