I have a dozen BR and Red Star chicks, about 6 weeks old. They are ready to go outside for a little bit during nice weather. I also have 10 adult hens, mostly BO and GLWs. I have the chick brooder/run within the main run for the adults, but sectioned off. I want to put some temporary fencing just outside the run so that the chicks can go outside to explore and scratch. I know you're not supposed to put the chicks in with the adults until they are about the same size, but is that a rule more for staying in the same coop, or does it also apply when they are outside? Will the adults pick on the teen chicks? Thanks!
