I've been thinking about that formative dynamic in the past few weeks since the four youngest arrivals to the chicken yard -- two Splash Marans and two Lavender Orpingtons -- were moved into the larger flock. Much like the freshman school, they had spent a time apart -- just the four of them -- living together in a separately fenced enclosure, sharing their own coop, eating their specialized feed, roosting beside each other at night, and competing with one another for bugs. Their special needs called for this separation. As new arrivals they needed to demonstrate that they hadn't arrived with diseases that could infect the larger flock. As considerably younger birds they needed time to grow in safety without getting challenged or pecked on by the older girls. And having arrived from their birthplace in southern Illinois, they needed to become acclimated to their new environment. For almost three months, then, they grew and matured and bonded in their own sequestered world.

Not entirely. One of the Lavenders has become emboldened to sleep at night in the larger of the two coops with the biggest crowd of older girls, leaving her three classmates to look after each other in the smaller coop into which they were settled. But come daylight the four are reunited. Indeed, they stay up together later than the others; they linger together by the feeders to share their meals; they hang out together in the run through the afternoons. They are, indeed, a united sophomore class.
I can't say if it annoys the older girls. Personally I'll admit to some mixed emotions about their togetherness. There is something to be said, after all, about blending in -- becoming "one" with the larger flock. But that said, there is something equally precious about having a circle of sisters who, together, "have your back", and who developed a low enough center of gravity to know that they can dance with whomever they want. Perhaps like the larger country around us -- less, as it turns out, a "melting pot" and more, as we are increasingly figuring out as a culture, a "salad bowl." These girls get along with the others just fine, but they seem to retain a pretty clear sense of who they are.
And as far as I can tell, they are going to do just fine. Just like the rest of us.
