Chicken tractors

[LazyGirl]

I am thinking about doing broilers for the first time. Someone gave us a bottomless wire cage that would be perfect. It's approximately 4X7 ft. How many broilers could i have in there, and does anyone know for broilers sqft/bird?
Thanks

It depends how often you want to move your tractor.

I'd say 14 max.
