You have a choice when you order chicks from some hatcheries, to vacinate or not. If you choose to get your chicks vacinated they recommend that you do not use medicated feeds as it will negate any effects the vacine might have. If you choose not to have your chicks vacinated then you are supposed to feed them the medicated feed. With all the possibilities of what can go wrong with chicks until they reach a certain age, it would be wiser and easier to have the hatchery vacinate your chicks before shipping.
