Hello all I need some advise! We have tried everything with no luck now my husband wants to lock up older flock in coop away from younger flock. I'm not hot on this idea because they can't be outside. But we don't know what else to do they peck at the young ones. We tried the seperater in coop and run and then try them all together and then they are back at pecking. We tried the free range with all of them and then when they get close enough they start pecking at them again. Anyone have any more ideas?
