I have recently ordered additional birds to supplement my current flock. I would like to introduce the new birds to the existing flock after the new birds reach about six to eight weeks old. I've read many of the "introductions" threads and most, if not all of them had introductions of a small number of new birds to a larger number of old birds. I'm planning on introducing 28 six to eight week chicks to 11 older birds. Another matching will be five older birds moving in to 27 six to eight weeks old chicks. Initially, the two flocks will be in two different coops. Eventually, I plan to break up the bigger flocks by breed, but not until later in the summer after I get other coops remodeled and built. Any ideas on what to expect? Will the older birds feel outnumbered and succumb to the younger flock; will the younger flock overwhelm the older birds? Will this plan even work?
