How do you train ducks to go into their house at night? Our chickens are free range snd we intend to allow our ducks to do the same once they are big enough. We have no shortage of predators here, from bears to bobcats, and so far we have only lost 1 rooster to a predator (middle of the day fox). My coop is elevated and extensively protected and it has withstood regular attempts by bears, raccoons, etc to raid it at night. I'm confident my low to the ground duck house will do the same, but what is the best way to get the ducks to go inside on their own?
