Trying to figure out what size I need to build for my chickens. I'm planning on keeping 3 chickens. (Either 1 full size and 2 bantams OR 2 full size and 1 bantam... Depends on what ones end up being hens) I read online if you don't plan to free range, they need 10sqft per chicken. So that would be about 5x6 ft run. Is that plus the nest/roost area or all of it? I want to free range but it depends on how well that works out (if they don't try to escape yard, predators, etc). so I want to plan for them not free ranging if it doesn't. ETA: I was also thinking about making a portable covered play pen I could move around the yard if they can't free range.
