I have too many chicks! My "favorites" are in the coop in a protected brooder so that the big girls and boys don't hurt them. I was left with a bunch of wanted but not super special chicks, and the brooders were full. They needed more room than what they had been in so I made another brooder and put it out in the coop What I did differently with this was I put all four corners up on large bricks. Giving about 4 inches of space all around for the chicks to run in and out of. The big birds can't get under there. I hung a 250 red heat lamp bulb in there and put a feeder in too. Now they just run in to keep warm or stay out of harms way when the big chickens get an attitude. Run out and get a drink. Everyone seems to be good with this and they are all getting used to each other in a safe way.
