Sorry all, one more question. My 3.5 week old ducklings are currently on chick starter/grower (18% protein) food as no one around here sells waterfowl food that I can find. The problem is that all the chick crumbles I've seen have tons of powder in them and I think it's bothering the ducks noses. I can sift it out I guess, but that means I only get like half a bag of food out of it Is this normal? Is there a better option for the little ones that wouldn't be so dusty?
