Well we put him in and he is much smaller than our 17 week pullets even though he supposed to be the same age. They pecked at him alot. He has a spot on his upper wing that didn't have fathers and they went for it. In about 10 min is was bloody. We took him out and put him in with 2 pullets and they still pecked him even with Blu-Kote. Hubby is going to move the cage close to where the pullets are and let him be there for a few days.
