Mareks Vaccine

[ChurpyChicken]

Does mareks vaccine work if the hen/chicken already has it?

Also can I give it to my other hens that don't show symptoms?

If it does..

where in the UK can you get it from/ship it in from?

They range from 6months to 6years old.

Most adult birds have already been exposed to it, that is why it says to vaccinate newly hatched chicks before they become exposed. Their is contrasting opinion whether it can help those already showing symptoms.... but what can it hurt if the bird already has it? I don't know where you might get it up there..... I order it from Jeffers livestock.

Hello ChurpyChicken. I am new to chickens and have no experience with the vaccine, but I searched this site and found a thread that gives some detailed information and should answer some of your questions. See post #3 in the link below. I hope this helps. If not perhaps someone with more information will come along soon.
