I decided to let a couple of my hens free range. I know a lot of people that let theirs free range. They assured me other than predators the hens will not run away and they will return to the coop before dark. I decided to let two of them out about 2 hours before dark to see if they would enjoy it. Much to my shock they ran back in the run within a few seconds. I left the door open and one went back outside but for an hour she basically stood right outside the run and looked confused. The other one I picked up and set outside again. This time she took off and I didn't see her for over an hour. Next thing you know she shows up and starts pacing outside the run. It's like they don't really like being outside. Do they have to get used to it or was it because the others were left inside. It kind of freaked me out. I have had them both for a year. They had never been outside the pen. The pen is about 25x30.
