I raise my own chickens for meat and eggs. They are just farm yard chickens... Roam around the farm eating bugs all day and they go back to the coop at night to roost.
I keep them locked up at night due to the coyotes, owls, bobcats...etc..
I used to have a pen made from pvc pipe and chicken wire. It had small plastic wheels on one end. I could pick up the other end and wheel it around the farm yard.
I called it my play pen. lol Used it for lambs, ducklings and chicks, even rabbits.... it worked great.
