So I recently bought 4 ducklings from a local fellow. Quarantined my standard 30 days and when all seemed good, put them out with the main flock - 40 chickens and 6 ducks, first in a “see but not touch” transition pen, then out with everyone else. Exactly 1 week later ( Sat) my 2 yo rooster got a swollen eye and mucopurulent nasal and ocular discharge. Then another rooster the next day. Now 5 roosters and 2 hens are sick with similar signs. Wheeze gurgle wheeze gurgle. I’ve been pilling them with baytril but I’m going to start flock- wide tetracycline in the water tomorrow. So I’ll have to pitch dozens and dozens of eggs and may end up with chronic carriers that could reinfect the flock. It’s just so depressing. I’ve cleaned and disinfected everything I could but I feel helpless. I’ve since found out this guy gets birds from auctions, sales, swaps and every other germ pit you could imagine. And mixes them all together. I guess the lessons are: 1) even a healthy looking bird can be carrying bad stuff and 2) know your source before you buy.
