I just built a 2 story coop (pictured below) and just put 2 one year old hens into it. They went from being in a large flock (30+) and they don't seem to like the new digs. They also dont understand how to use the ladder to change floors. Any suggestions on helping them to be comfortable in their new home? I also have some pullets that will be introduced to the coop in the future. Any suggestions on how to have a successful meet-and-greet with the current tenants is much appreciated.
