How do you raise meat chickens????

Why can commercial meat chickens normally grow their table weight around 7 weeks? Small farm or back yard chickens to grow will take twice longer than commercial chickens.

Do they use some growth hormones or steroid for commercial chickens? In the most famous chicken meat companies say that they will not use any growth hormones or steroid in their companies' mission or values. If they won't use those, how they can grow so faster than natural or small farm chickens?

Do chickens eat any fresh green vegetables? It is important to give Protein, Carbohydrates and calcium etc. Which kind of vegetables is the best for chickens? I am asking for meat and eggs, both. Do they eat raw green vegetables or cooked, prepared green vegetables?

If we go to Organic market as "Whole Foods", does this mean their meat took longer for growing than commercial meat?

What is the normal size for meat chicken and egg chicken? I know that it will be different on each chickens. I am asking as the average.

Please give your answer and instructions to my question. I really appreciate it.
