Hopefully this is in the right place... I know the suggested sq ft for coops and runs. I'm curious what a decent amount of space would be for hens to free range part of the day without destroying the yard. I hear of most city dwellers getting about three chickens (often what the city allows), but in Seattle, at least, most of the lots are very tiny (IMO). Our yard is about a quarter acre, more than half of which is fenced in the back. Does six chickens seem like too many for this space? I started out planning to get 3-4 chicks and then convinced myself it would be fine to get more. Now I'm not so sure. (We don't have them yet).
