Is bio-security an issue with hatching eggs?

[mamaKate]

If I buy eggs from a breeder, do I need to quarantine the chicks when they hatch? Would it be safe to place the brooder in the coop?

Seems like a good idea to wait at least a couple weeks before putting in with the flock or coop. But if you know the breeder and they are reliable and tested it may not be a issue.
