Got up this morning and all 6 of my ducks are gone. They do not fly and were full size. They did not go into the coop last night. Upset for not putting them away. What takes 6 ducks? Yard is fenced. Would a pack of coyotes take all. did not hear anything. There were some feathers under the coop, but no blood. New to the state of Missouri, what takes 6 ducks?
