Bought five "pullets" at an auction. No probs. today I go to let the girls out and they're not waiting on me. All are in the coop, except one making patrols. I open the doors and do a head count. I call, but no one will leave the boxes. Finally they venture out, and after a minute the one in question grunts and they all run back in. Two days ago I had no question that it was a pullet. Now...?
