I am getting a very small flock from a hatchery and am not planning to vaccinate (because the hatchery advises against it for some reason), but if I EVER want to add a new cluck or new chicks next year, I'm not sure how to go about it. Here are my basic questions about quarantining new birds before introducing them to the flock: 1. How far away should the quarantine area be from the existing flock? 2. If a seemingly healthy bird from a friend's flock is quarantined, will it display any disease it has been carrying within 30 days after it's removed from its old flock - even if it was never sick with the old flock? I'm not sure what to look for - if the new bird doesn't get sick in 30 days - does that mean it's not carrying anything that will make the existing flock sick? With all the talk (over my head) about carrying a disease but not getting the symptoms, etc., I don't know how introducing a new bird could ever be safe...even after a 30-day quarantine.
