I have 13 chickens that I need to give away or sell (12 hens, 1 rooster). I have someone that is interested in taking some of them. I'm hesitant to separate the flock. They've been together here with us for over a year now. Do I have a valid concern, or will they be just fine if separated? The guy who wants them has a fairly large flock of his own already. So not only would my birds be separated from their own flock, but will also have to adjust to a new one. What do you all think?
