I got my Meyer catalog today and in 2 places that I saw, they say that you have to figure on 1-1.5 sq feet per mature bird. This is why there is so much confusion. It's not 1.5 square feet per bird. It's not even that for Bantams. Gee they take more room than that in my freezer. People, be good to your birds, give them 4 sq. ft per bird.
