Hi folks, brand new here, brand new to chickens. I had 21 chicks sort of fall into my lap a few months ago. We've been figuring things out together as we go along. Up til now I've been able to google for most of what I needed to know, but the last two days I've noticed a couple of my chickens doing the weirdest thing! One chicken will stand perfectly still while another pecks at its beak and face repeatedly. The one being pecked doesn't react at all. I just noticed it last night between 2 of them, and tonight 2 of them stood still while a third pecked both of them, alternating between them. I tried to google it but I just get a bunch of "pecking order" results, but this is not that kind of pecking. What on earth are they doing??
