My husband and I were thinking about adding ducks to our backyard poultry extravaganza, but, after reading the Storey's guide, and looking at various websites, we have heard so many different things about ducks and ponds that we are dizzy. Sooo.... How big does a duck pond need to be? How doy you deal with muck build-up? I've heard of people using a kiddie pool and emptying it daily, but everything I have read says kiddie pools are insufficient. Does this really work? We would be looking at 6-12 Anconas.
