I would love some tips on the best way to introduce a new hen to our young flock. We just came to realize that one of our beloved RIR hens, "Loretta", is actually a "Henry!" Even though he doesn't know the words yet, he's been practicing his cock-a-doodle-doos in the coop every morning and that a big deal breaker for our new backyard flock. I have someone interested in adding him to their flock so we don't have to worry about culling him or someone eating him but we want to obtain a replacement, preferably a Barred Rock since we like them the most out of our 2 RIR's, 2 SLW's, & 2 PBR's. We want to keep the hen count at 6 since we're in a joint venture with our next door neighbor and will want the egg supply. I think I can get a new hen from some local breeders that are close to the same age as our flock or maybe a bit older. How should we introduce the new addition when the time comes? Anything I should worry about?
