Hi Lindsey, I would have to agree with what Shawna (minimule) said. I have a hinny and he dont quit know what sound to make either, but when it does come out it really does sound more like a horse, trying to whinny...but not quit succeeding. My mini donkeys all go in the barn when the weather gets cold, not even the run in ...in the barn in a warm stall! They dont seem to have the winter coats like the horses get. Besides that ..we wouldnt want them to get cold ears!!..lol...as for ducks, mine would probably chase and stomp them, they dont like anything that dont belong in there pasture, even a barn cat just crossing thru, they will chase right out. I would put the ducks in there own penned area. HAPPY HOLIDAYS! Corinne
