I was so glad to see this realistic article. I totally agree that it is best to give them as much space as you can. I have seen so many things that say 2 or 4 square feet per bird or some foolish thing like that and I know MY eight girls would not be happy in that situation. They love having their large pasture. I cringe when I'm on the road and see the little 4'x6' coop/run units from the local farm store and 6 chickens in it. I'm fairly certain that they are NOT happy birds, but the manufacturer decided that coop/run unit is for 8-10 birds and advertises it as such. I saw one online that was an 8x10 unit for up to 18 chickens! Wow!
