Unvaccinated added to vaccinated chickens?

[Chic Chick]

Is it safe to add an unvaccinated chicken to a flock of vaccinated ones?

Anyone?
I'd feel bad if a sold a roo to someone that has a flock of vaccinated hens and the roo died.

Vaccinated for what?

Yes, we have to know what they've been vaccinated for. For cocci, no problem at all. For ILT, would be a whole different ballgame.

The hens are vaccinated for mareks and coccidiosis

If the vaccinated ones were properly quarantined after the Marek's vaccine, they will pose no risk.

Thanks for your answers. I was worried because those hens were raised by the hatchery to pol so they could be carriers of any disease. She's coming tomorrow to pick up the rooster so I hope it will be ok.
