Yeah, I am not sure about certification. Last I checked there were different rules depending on how much you're selling, too. As far as plants go, fields have to be chemical free for quite a number of years before anything can be considered organic. I would have thought it would be different for animals, since chemicals are gone from their bodies quickly, unlike soil or water sources. If you're talking about wanting certifiable organic, you'll have to really look into that. If you're talking about organic chickens just because you think it's best, I wouldn't worry about getting conventional chicks.
