I'm debating whether to add a new hen to my flock, but I wonder if I can cut down on the quarantine a bit. I added 4 pullets to my existing flock back in August, and this new hen would be from the same breeder/farm. Would that mean that my flock is already exposed to most of the microbes/bacteria carried by the new girl? I'm growing out new chicks and with the temps dropping, I'd really rather not have 3 separated groups for too long. Thanks so much for your advice!
