I have heard a lot about the vaccine, and unfortunately, we have Marek's in our flock. So I was wondering, where would I be able to get the vaccine? Do we ask the vet clinic, or can we order it online? I know the one lady my mom talked to said you can only get it in doses for like over fifty or a hundred birds. We have five eggs under a broody that are set to hatch next week sometime. I know its silly to buy that much vaccine, especially when its a one time thing, isn't it? Like after you activate it, you have to either use it all or dispose of it by burning or something? But i feel an ounce of prevention is worth a pound of cure, or in our case most likely a pound of dead chicks. So any hints on how to administer the vaccine, and more importantly, how I can find some? Thanks for any help you can give me.
