I moved my second flock of chickens in with my old flock because of predator issues. I did this about two days ago and everyone is living peacefully. Every morning I let my old flock out because they free range and keep the others locked up since this coop is about 50 yards from their old coop. How long should I keep this up? My layer flock is getting upset because they don't have constant access to the nest boxes and now I'm afraid they will learn to lay somewhere else. I don't want the others to get lost. I cannot keep everyone locked up because I have too many roosters, they will go stir crazy, and their coop is only for bedtime. They free range on my property and even hide in the woods during the rain unless it's a really bad storm. Suggestions?
