Okay, its winter, but they are getting out a bit, they're in an old 20x30, 2 room cabin ....25 chickens... (Not too crowded, I don't think) All of a sudden I see a bunch of feathers, and a hen gobbling them down. I've been working in the coop on and off all day, and again about an hour later, GRAB, Gobble... DISGUSTING!! They have PLENTY of food! A couple others joined in the feather eating, but it seems to be a certain EE'er doing the damage. What the heckZ???
