We've got four hens, 2 barred rocks and 2 buff orpingtons. No roosters. They're more pets than anything, but do produce eggs for us and are so much fun to have! We've had them for a year, since they were pullets, and I ADORE them! So for the last couple of days one of my buffs is exhibiting weird behavior. She hangs out in the nesting box, feathers all puffed out, squawking and clucking. When I take her out, she doesn't stand right away, just kind of plops down where I put her. Then she stands up, shakes out her feathers, walks around, drinks, eats, and goes outside in the run with the other girls hoping for a treat. When she's around the others, most of the time she puffs herself out like a big Tom Turkey, wings out and down, feathers standing up, tail fanned out. She'll charge them, too, on occasion, which is new-- they all got along perfectly well before the last week. She's not laying, and she's not sitting on anything. In fact, production is down among the whole flock, which is odd because they were laying like crazy a week or so ago. She constantly clucks, and will run back to the nesting box and climb right back in. Oh, and she is doing a LOT of grooming, suddenly. In fact, she seems to have pulled a lot of the soft downy feathers out of her lower abdomen, like right where she'd sit on the eggs. I'm not that worried because she's eating and drinking and her color is fine. But if it is broodiness, how can I stop it? Or should I stop it? I really don't want this to go on for months!
