Hello! Our sweet roehn duck Ramoncito dissappeared the other nite from the fenced in chicken yard. I had just recently taken off the deer netting that covered the top. He had no reason to leave his best buddy cayuga duck Soy Sauce, or us, all was well. He just vanished. No feathers, blood, struggle signs, nothin'... Did an Owl get him? Do owls eat full grown big ducks? Anyway, how would we introduce another duckling into the family? Thanks for you time.
