Why does Horizon use chicken?

AAFCO Definition:   the clean combination of flesh and skin without accompanying bone derived from the parts or whole carcasses of poultry or a combination thereof, exclusive of feathers, heads, feet, and entrails.

Chicken is a highly digestible protein source for dogs and cats.  Horizon sources the same chicken that is provided into the human food chain.   Chicken is a lean meat and is extremely dense in nutrients including protein, zinc, iron, magnesium and phosphorus.  Chicken is also a good source of the cancer-protective B vitamin, niacin and the important trace mineral, selenium.  Selenium is a very important mineral for antioxidant defense and immune function.
