I understand hatcheries will inoculate for Marek's for an added fee, but what about breeders? I would think they inoculate their own birds so will they inoculate the day-old chicks they ship out or, does this depend on the breeder? If they don't inoculate, would it be necessary for me to take my chicks to a local vet? Are there any other diseases that require inoculations? Or is this taken care of by feeding the chicks medicated feed? I'm still learning so any enlightenment will be greatly appreciated. Thanks.
