I have a problem getting my call ducks in at night. They do not have a duck house, each evening I lure them in with my chickens, geese and turkeys. It is quite a challenge, often resulting in my DH and myself chasing, capturing them, and putting them into a run. We have a predator problem. I can build a house and float it but I am afraid they my wander onto dry land and be somethings diner! Any suggestions?
