Chicken to Square Foot Ratio

What is the amount of area (of new pasture) each chicken should have on a daily basis? I want to know how many chickens should ideally be kept in a tractor with a 10'x12' foot print.

I wouldn't do more than 6-8 chickens and moving every other day. It is surprising how fast they can eat the grass down inside their tractor run.

Do you suggest supplementing with feed other than grass, or can I plant the right stuff in the pasture?

My girls eat less store bought food in the summer, but it is always available to them. The field that I move them around in has been mowed for hay in past years, so the grass vegetation is quite thick. I also use standard city type fencing tied to T-bar posts to move them around. Chicken tractors are to much trouble for me, but work well for others. Just don't let them eat it down to far as the grass will be slow to recover.

Thanks!
