Mallard, pintail, and goose butt-up decoys have been around for ages. Now I see that GHG has green and blue wing teal butt-up feeders out this year. Who of you would buy, and if you did how many would you put in your spread? Most of the teal I see feeding just surface dabble, but maybe they butt-up feed more than I know of. If you run mallard butts, how many?
