Back to the original discussion... It's not just about square feet per bird, but overall space. While you might possibly be able to keep 2 chickens in 2 square feet, it would be better to keep 100 chickens in 100 square feet.
In a 10x12 pen (120 sqft), I kept around 70, which is a lot of space until the chickens get to about 6 weeks. A factory-farm may have something like 20,000 chickens in 20,000 square feet.*
So... for a 4x6 area, 10 is a reasonable amount, but as a rule of thumb, 2 square feet per meat chicken should work fine.
Yes, I said a lot just to agree with everyone else. I just wanted you to have a better idea of where we come up with these numbers.
*Personally, I still think that's overcrowding, but they make it work.
