You can rig up a chicken wire pen within the main run for the bossy GLW--which,incidently is how I meld my chicks into the main flock. Once the chicks are off heat, I use a dog cage in the coop at night and then put them in the inner pen during the day so everyone can see each other. After a week or two, one invariably escapes--and either gets chased back or ignored. When they are ignored, they are safe and they know to go into the main coop at night!
