I have recently acquired 11- 4 month old chickens. My other chickens are 1-3 years of age so I planned to separate them. However, the smaller group must have a different plan. lol I have a large area (if you can imagine) and on each side is a coop plus a small run. One for older one for smaller, The middle is the big run area. Every morning I am finding the smaller girls in the middle or in the other coop. I have tried everything I know to keep them on the other side but they must be flying over the gated area on their side. My concern is them eating the layer pellet and not enough chick food. I have them on the "teenage" year food. Also I gave up this morning and just left their gate open since they all get along. Will it hurt my older girls to eat the chic food? I'm at a loss.
