We have 6 chickens who have been allowed to roam all over our yard. That's been nice, but now I am really getting sick of all the chicken poop in the yard and on the walkways. These chickens think they are own the yard. If I want to fence them into an area/pen, how are they going to handle that, since they've never been contained. Well, they are locked in the coop at night, but free range once let out. Will they all fight with one another? Since roaming all over our huge yard and woods has been normal for them, what size should I make their outside enclosed area? edited to add: I have one hen who is older then the other 5. She was here before the little ones, who aren't so little anymore. They are all laying now!! But the older one is the boss and pecks the younger ones. Just want to add that in consideration of pen size.
