Okay, this is probably a really dumb question, but I'm really new to this, so please bare with me.
We have a large (for the suburbs) area that we are going to pasture our chickens in. We live on 1/3 acre, and about 1/4 of that is going to be just for the chickens, so I guess that's, what...1/12 acre? Anyway, we're planning to let the chickens roam free in that area all day long, and just put them in their coop at night. Do we need to build an official run, or just a place for them to sleep and eat?
