That's what we do now. I was putting broodies in a pet pen on our gravel driveway but there's no shade so when summer hit, hubby set me a wire pet cage on bricks in the dog kennel. A bucket of water is tied to one corner, small feeder in the other, and a 2x4 on the other end for them to perch on so they aren't standing on wire. Usually 2 days does it, but sometimes 4.I hope you break them quickly! I know theres a few tricks to doing it. A wired cage bottom hanging up sounds like a good one to me.
