Hi - This year I am going to start to vaccinate all my chicks. I hatch from March until about July and each hatch is only 20 - 50 chicks. I understand that once you start to use the mareks vaccine that you need to use the entire contents in 3 days and then discard the rest. I can only find 1,000 dose bottles. My question: does anyone know of a smaller doseage - maybe 100 dosages per bottle?? Thank you for your help! Laurel
Hello-- I think most of the MDV-3 Marek's vaccines must be used within an hour of mixing the virus, not three days! Be sure to check the instructions carefully. It'd be very upsetting to spend the money and think that the chicks are vaccinated properly only to find out otherwise! Administering the vaccine improperly won't protect the chicks. Anyhow, no, at this time there are no vaccines with doses smaller than 1,000 for Marek's available to the consumer (you and I). I don't even know if hatcheries can get smaller dosages. Probably not. It stinks when you only have a few chicks to do! I've bought it for only 4 chicks, before.
