I used a dog crate turned upside down, so there would not be a "floor." I lined the bottom with 1/2-inch hardware cloth, because the wires were spaced too far apart for her feet and put a roost bar in it. Since I have hatchery birds (both Barred Rocks who tried out the broody thing) it only took 2 days in the "breaker." I didn't dunk either of them, just picked them off the nest & put them in the cage with food & water. It was in the run part and up on pieces of 2x4 because I could not hang it. I put the crate's floor on top to keep her "sisters" from pooping on her.well that cornish got over her thing i guess she figured everyone else was up there being broody she would try for a few hours..thank god what are the tricks for breaking a broody just in case i don't need a 15 lb chicken getting an attitude when there is no eggs for her...
