Chickens are given neither hormones nor antibiotics. It's been illegal to give chickens growth hormones for a long time. Most major chicken brands (Tyson and Purdue, who are #1 and 2 in terms of production) do not give chickens antibiotics, unless the flock gets sick. In that case, the flock is treated and then sold as a different product- usually either as pet food or an off brand. I don't know why we use hormones and antibiotics for pork and beef but not chicken.
