I have a young chicken, maybe 4-10 weeks old that I got from an auction with a bunch of others. They all look a bit on the scraggly side, but this one is the worst. It's whole underside from under the tail, down the insides of its legs, and up its breast bone is feather-less and the feathers still present are stained brown. I soak him now and again and today tried to rub him clean with a wet towel covered in Dawn dish soap. I have him resting in the garage to stay warm since it's chilly tonight and he isn't dry yet. I figured he would be looking better by now since he's in a much cleaner environment and has some room to run around. Out of the 12 I got, he's the only one like this.
