Not only did he establish a firm leadership, he did it with little aggression or fanfare. What was truly impressive, though, was the change in his appearance. I don't know if it's hormonal or something similar, but after stepping into his new leadership role, Rocky seemed to morph from Rocky J. Squirrel to Rocky Balboa overnight. (que theme music). His feathers grew fluffier, more numerous, and more colorful, his size seemed to double, his comb grew larger and redder, and he grew ankle feathers. With Spartacus out of the picture, Rocky exploded onto the scene and declared victory.
The only concern I have is that he isn't as actively engaged with the hens who wander farther out. He tends to stay near the egg mobile and the barn. We'll see how he does. Hopefully, he learned from Spartacus' mistakes and will be around for a long time.
