Our girls are about 11 weeks old now, we have 6 EE's. We moved them to the new coop a few days ago and allowed them to range for a couple hours today. Ranging went great, and they returned to the coop on their own at dusk. While they roamed the yard I noticed that their tails were all straight up, as opposed to flat when they're indoors. Tail position has meaning in other animals, does it mean anything in chickens?
