No a Grower/ finisher feed at 16% for all Birds works. Plus lots of forage material..I was told that earlier, that's why I started adding the oats. I don't know that such a thing is available in my area... I've been feeding all my ducks Purina Flock Raiser for years. Maybe they have it as a layer feed, but it's my understanding I can't use that since I have drakes too.
