We have 12 free range chickens between the ages of 9-10 weeks. 3 Ameraucana/E. Eggers 2 Gold sex links 2 Barred Rock - 1 is a rooster 1 Black Sex link 1 Leghorn 1 Buff Brahma 1 SL Wyandotte 1 Polish Bantam They all get along excellently. Still establishing their order. And we have two coops, they sleep in one all together right now as they are still small, but as they get bigger I want to move half to the other coop so they have more room. They all go up into the same coop at night on their own. How can I train some of them to go into the other coop? Thanks!
