I do have an attached coop and run and we are currently building a twelve foot long by six foot wide run for them and then we are going to add on to the existing coop where it currently is to give them more space. There is an open door with no way to close it off to keep them in but once they are out in then they stay in. I noticed last night that they all gathered in and around one of three nesting boxes. We had some ugly storms last night so I checked on them in between the rain. They are fine. I'm hoping they catch on soon and go in on their own.
They will, if they were by a nesting box, you have the battle won.. Wait until you get turkeys and have to teach the teens they can't stay out all night...That is a battle royale!
