However, because some feeds specifically advertise themselves as "hormone free," that begs the question for the other brands that don't mention it: "Do you use hormones in your feed?"
They do NOT.
Some commercially available chick feeds will contain medication. When they do, it is usually a coccidiosis preventative, and will always be listed on the label. In fact, most brands have both medicated and unmedicated versions of chick feed, so you can make a choice--but no hormones.
Rest assured that the Extension Service confirms that there are no hormones in your commercially available poultry feed.
