My girls were rescue chickens and the dumb bleep had 12 girls in with 4 roosters and a 4x4 space! So when we got them their poor butts and backs were really bare. They kept getting sunburned and then the pecking order took some of their other wings and butt feathers. So I got the aprons to keep them warm, stop my rooster from hurting there backs, and keeping the other girls from pecking them. I watched them in action today! My rooster kept sliding off them so he couldn't throw down as he usually does. He yelled at me for it. Ha!
