How does buying these foods benefit the treatment animals?

In factory farms, animals are generally treated very inhumanely. They put as many animals as possible into a small space, to maximize profit. They also tend to kill animals in inhumane ways, and treat them badly while they are still alive. Since chickens are kept in such tight confines, they cut their beaks with a hot blade, because they peck each other when put too close together. Also, pigs have been been known to be kept in cages where they can't move for the length of their pregnancy. Buying at local farms can prevent this cruel treatment of animals because they usually have enough room to live and are treated much better.
