How long should I keep birds in quarantine? I'm planning to get some adult Muscovy ducks, a few silkies, and maybe some turkeys from a swap meet on the 14th of April. How long should I keep these birds in quarantine and what should I look for when they are in quarantine? In previous years I have not thought once about new birds bringing in illnesses and I would just add them to my flock on day 1, I realized that might not be the safest way to do things.... So can you guys give me some info about keeping birds in quarantine?
