Can someone explain to me what is happening when several chickens run up to another, pin her down for a few seconds, and then once the ordeal is over they all act like nothing happened and remain in close proximity to each other. Mostly, this happens when they are free-ranging outside the coop. The pinned chicken just shakes it off with no damage done and goes back to grazing. I have 7 hens that get along pretty well and I understand the pecking order drama within flocks but this seems to happen randomly although the matriarch is never the victim of this. What did the offending chicken do to cause this reaction from the others?
