Today is the third of our flock to disappear and show only a pile of feathers as a result. No blood, carcass, just large amounts of feathers. The girls free range in the day and get locked up at night. All three seems to be happening at dusk. We live in central Texas out in the country and have a hog fence around out property. Could someone please shed sown light on this?! We lost our best layer pinkie pie last week and Snow White tonight . Thank you!
