I came home today and a mink got my ducks. How do I know? A few months ago a ton of my chickens were gone. I looked under the shed and they were all under there with their heads gone. I set a trap and caught a mink. Same thing. The ducks are under the shed, with no heads. What time of the night do they come out. As soon as its dark or almost day light? I set a trap with a chicken in a separate cage. The chicken WON'T BE HARMED.
