On Saturday I am going to be picking up my first chicks. They are a group of 3 Gold Laced Wyandottes pullets and 3 Easter Eggers pullets. I am also getting an assorted mix of 8 Bantams, breed and gender unknown. Their indoor coop will be about 9 ft x 9ft with roosts that go up as high as 7ft. What I need to work on is the outdoor run. Currently the area is connected to a 50ft x 100ft run with a 5ft fence. That encloser is inside an acre and a half fenced in area with 5ft fence as well. I can make a little coop that has a top cover instead of the big run, which I plan to do to acclimate them to the outdoors, but what is the likelihood that close to 2 acres of fences will keep them relatively confined? I have a working farm with horses and goats, but the chickens are new. I do know that there is a greater chance especially of the bantams getting out but their primary goal is bug control so while I will be really sad if something happens to them, I would eventually like tyo get them out in the pastures.
