Given the market value of "organic" or even "free range" if their product contained it then they'd mention it. Assume it's a low-cost chicken. "Natural ingredients" is fairly broad:
"The USDA has a legal definition for "natural", but it applies only to meat and poultry; "those products carrying the “natural” claim must not contain any artificial flavoring, color ingredients, chemical preservatives, or artificial or synthetic ingredients, and are only “minimally processed” defined by USDA as a process that does not fundamentally alter the raw product.""
