I need to get more female ducks to add to my duck flock. I have been concerned about Bird Flu possibly spreading again with the migratory birds. I do NOT want to get my 12 very healthy ducks sick. I have quarantined 2 new groups of ducks before letting them meet the rest of the flock. My ducks have very little contact with other birds in general other than sparrows and finches stealing their food. Is it safe to get new ducks? Am I just being an overprotective duck parent? Any advice is very helpful. Thanks!
