Along with what Sally said, maybe try putting them in an entirely new brooder, one at a time. He might see the brooder as his home and these 3 other chicks are intruding. Not sure if they develop that kind of possession that early but it's worth a try. Either way, in a couple days I think they should be strong enough where they can get away if they are being picked on and after a day or two of being together they will be fine with each other.
Do you have any way to provide heat without a light? It might also help if you can introduce them when it's dark. Works pretty well with adult chickens so I don't see why it wouldn't work with chicks.
