Ducks that land in the middle of a big pond

[Gottogo49]

Thanks for all the suggestions, it's my buddy's lease where it happens the most. He tried the scareduck and it worked pretty well. Another pond that I have been able to hunt has a similar situation but we are killing limits most every hunt anyway. There are about 200 resident coots and the ducks pile in with them where ever they are. The coots usually swim over and hang near the middle while we are hunting.
