I've got a bit of wet land upon which I'm thinking of building a duck flighting pond. Anyone know how big and how deep it needs to be to attract duck ? I know the sides need to be gently sloping but what else should I consider ? How far back do I need to cut the trees around it and in which direction ? Long and thin or perfectly round ? Tried googling it but all I come up with is how to make a pond for domestic ducks. Where else can I get the info ?
