Is it true that if you eat a lot of chicken, your will get bigger?

Chicken produced in the USA won't affect your size. However, in unregulated countries, they give the chickens so many growth hormones that the girls get at 9 and 10, and the cancer rate is 10 times the US average. I refer to Bahamas, as a point in case, having lived there I know this from talking to the locals and also from reading the results from government studies. Be glad you are not faced with that problem, as the USDA regulates what chickens raised for food can eat.
