New chicks and mareks vaccine

[BGR]

my husband brought home three chicks two are downy, no feathers, the third is probably two weeks older--has wing and tale feathers. They were part of a "wild" flock at a local horse barn, so no vaccines. Is it too late to have them vaccinated? Do they need to be vaccinated?
