I have yet to use these . Not supposed to hunt ducks in summer time . But I assume these will go great in my spread as an eye catcher being very visible to ducks at distance for as gigatoumous and dark in contrast to other quackers. A three pack seams natural to me. As I have only spotted three black ducks at a time ever and only a few times at that here in Northern Michigan. I'm not expecting to pull in many B/D with these. Mostly it's just a conference booster as B/D are very cautious about sketchy places to sit and chill. Probably just helping my Malard game. And that's enough for me 🦆
