Hi, all. About a week ago we had two female ducks come to our yard and settle under our deck for the evening. My guess is that they came from our next door neighbor who picked up and left in the night, abandoning both cats and ducks and left them all to fend for themselves. We know a thing or two about cats, so they're no problem. But we know next to NOTHING about ducks. We've had chickens before (and the ducks are now safe in our chicken run) but these girls are a complete mystery. Advice?
