I'm considering adding a duck to my flock and I'm wondering since all my chickens are vaccinated for Marek's I'm curious do ducks get that as well ? Should I do a quarantine for any new bird no matter the breed before putting any other type of bird breed with my chickens ? Wondering what the protocol there is ...thanks 

All birds have different personalities. Some are more accepting than others. Just be prepared with a plan B if they don't all get along.
