Vaxxed and unvaxxed chicks

[FrankeFarm9394]

Hi all! So we have 15 babies coming from MPC next week — vaxxed for Mareks. A local lady had silkie/EE cross chicks available and we got three of them that are obviously unvaxxed and I would love to get some babies from TSC — assuming they have any of the chocolate orps still available today or in the near future. Is it ok to mix the babies like that? We are in Texas and our adult flock has had zero issue with illness but they’re all vaxxed. Should we worry about it?

Thanks!

I personally wouldn't worry about it, I think they're all fine.

The Marek's vaccine is a leaky vaccine, doesn't protect against infection or transmission, only mitigates symptoms. It's unwise to mix those vaccinated with those unvaccinated for Marek's.
