We could not find any feathers or anything.May have been a wessel or snake.I don`t know.Was going to sale these and they were laying.Found them this morning,just laying out there dead,and lost 3 little quail,,Don`t know why,,,
If they were free range, my guess would be an owl. They get them at night and NEVER leave a trace. If you have tall trees nearby, you usually can walk around and see the feathers where they ate them.
