If you are getting ducklings then try to buy duck starter it will have the extra niacin ducks need to help with leg issues they can get when eating chick or chicken feed. if you ca't get that then get an all flock and just add brewers yeast to their feed or niacin to their water. But don't feed ducks under 5 months old layer pellets. too much calcium, wait till they are around 5 months or after first egg to feed layer. I use Flock raiser which is an all flock feed and put oyster shell out for my egg layers. And
