Okay, I have two separate flocks who may have met before, but I have never seen it. One is made up of 6 hens and 1 rooster, the other is just 6 hens. They all free range during the day, but their coops are about an acre apart and only the rooster goes from flock to flock. I have never seen any of the hens within 50ft of each other. I want to merge them all into the coop with the rooster, but don't want a huge fight to break out. So whats the best way to get them familiar? Also whats the best way to keep them from returning to their old coop at night? Thanks!
