I'd call it: Chicken class, day deux

Let's say you've got your backyard chicken flock--anywhere from three to six birds--and you want to introduce a newbie.  Keep in mind the phrase 'pecking order' came from chickens and yes, the little beasts will in fact peck their new friend to death rather than share their food with it.  But wait . . . .

Let's say one of your birds is a broody--meaning she basically lives to hatch eggs.  Sneak into the coop one night (chickens are basically brain-dead in the dark and they'll be none the wiser), and put the same number of fake eggs under Miss Broody as you'd like to introduce new chickens into your flock.  Miss Broody won't know the difference.

After 21 days re-enter said chicken coop, again at night, dig the fake eggs out from under Miss Broody and insert the same number of chicks (conveniently purchased earlier in the day from a farm store) and VOILA!!
In the morning Miss Broody will wake to her chicks, delighted that they have finally hatched.  She'll raise them in the flock, teach them the ropes, fight for their social standing and basically pave their way into chicken society.

This is but one small glimpse of chicken hierarchy, and I've gotta say.  Who knew that everything you needed to know about navigating the world is there for the studying in the socially hardwired rules of a chicken yard???
