Mareks Vax Dosing

[BlossomSilkies]

I suspect we had a death from Mareks in an adult rooster, although unconfirmed and now possibly a chick hatched 5/23 with some symptoms.

I have the vaccine and plan to do the whole flock.

What amount would I give the following:

Standard size adults
Bantam size adults
Bantam chicks
Standard chicks

And is there any harm in vaxing any of these if they had been vaxed previously?

If your chickens were already near that rooster, they've all been exposed and the vaccine won't work. The dose is 0.2ml per chick or chicken, any size. Vaccinating twice won't hurt them.

If your chick is under a week old and the legs slide apart, it's spraddle. Most of the time, chicks will not have Marek symptoms till they are at least 8 weeks-most of the time.

Thank you. That is what I gave them and also will remember for next time. No one comes here ever again without having been vaxed and chickens hatched here will be vaxed.
