I haven't found a firm answer on duck poop. I hope that my young dog and ducklings form a strong bond and when the ducks are grown I can let them forage in the dog's 30 x 18 foot dog pen which the dog has access to via a doggy door in the house backdoor. Yet my second concern after if they will be able to bond, is the duck poop. I don't want the dog to get sick, nor roll around in it. Will 3 ducks poop to the point that keeping up cleaning after them will become unattainable? Do they poop constantly? Or can they be put on a schedule like a dog? I know these are odd questions, but finding out know will allow for me to build the best habitat I can. Thanks.
