A " friend " dumped off his ducks to me about a month ago and they were young then.. Now they are starting to fly! I hadn't planned on getting ducks, therefore, don't know much about them .. yet .. so, I've heard you need to clip their wings ??? They've been flying for about a week now, but just around their pasture area.. they don't go too far and are always back at night in their coop.. So, just wondering if it's essential to clip their wings.. or not!
