I turned my small-dog-size dog crate into a brooder. I lined the sides with 1/4" hardware cloth and also made an elevated "floor" of the same thing. The crate has a plastic tray that slides out and with the elevated floor, poop and scattered crumbles and any water spills just fall down onto the tray. It's really, really easy to clean. All I have to do is take the tray out, change the newspaper or paper towels, and slide it back in--don't even have to open the door. I also put a couple of paper towel stacks (3 or 4 towels) for them to sleep on and to give them relief from walking on the wire. Don't know if the wire's bad for them, but this just seemed like a good idea to me.
My only complaint is that my "floor" is uneven because hardware cloth isn't very sturdy, so I have to prop the waterers to make them sit straight. When I do the next brooder (am going to also modify my German Shepherd's old crate since she doesn't need it anymore and these babies will get cramped in this one pretty fast!) I'm going to figure out a way to put something under the hardware cloth to shore it up. The babies sure like this one, though!
