I had only 1 bantam cochin chick hatch out of 6. I put a wire screen in the brooder between the new chick and 7 week old chicks. That lasted about an hour and the new chick is screaming it's head off. I put him in with the others, even though he is about 1/4 their size. So far they seem ok. Do you think this will work in the long run or is it likely that they will start picking on him?
