My chickens don't just "groom" me, they preen me! If I'm carrying my white orp and ruffle her bum feathers a bit, she closes her eyes and tries to preen my arm. It's quite an odd sensation!!! Unfortunately, she also tries to get my attention with a sharp peck and it HURTS. What kind of bonding is that?!!? I'm probably going to be turned into a crazy chicken lady, too. When I talk to my chickens, they talk back!!!
