I recently bought 3 ducklings and was curious if you could train them like my guineas when it was treat time by ringing a bell. when the guineas hear this bell they all run to the side of the pen and await their millet and mealworms. What do ducks prefer to like as a treat? Im hoping that my ducks and guineas get along once they are introduced to each other, but that will be a few months. Thanks for helping with any advice....my family think i have lost my mind getting these kinds of animals as i am middle aging.
