Hi Anniekc I'm no expert, but since nobody else has chimed in.. I've been to two feed stores here looking for duck food with no luck, but they both told me to feed "broiler" chicken feed, because it has more protein, which duckies need. Mine have been on that since I've had them, but it's only been about two months so I can't really say how it works out in the long run. I found this thread because I'm trying to figure out something better. Right now mine are on Scratch and Peck broiler chicken food. It's the only non-gmo feed I could find, but it isn't vegetarian, and it has a smell that I really can't stand - the girls aren't crazy about it either. Is anyone making their own duck feed? I found a recipe here but I don't understand all the ingredients... "3.5 lbs fishmeal 1.5 lbs of Poultry Nutri Balancer .5 lbs of Kelp meal 5 lbs of Aragonite 1 lbs of either Molasses or vegetable oil (he said its best to use vegetable oil with waterfowl) Add above to 50 lbs of scratch grains or small grain blend. Example: scratch grains or better yet a combo of 50% wheat/25% oats/25% barley. You only need to add fishmeal during pre-lay and lay periods." (lay and pre-lay periods?) The first ingredient listed in Scratch and Peck is organic peas, which makes sense since they're so high in protein. I would love to do fermented grains for them, maybe ground into meal. They free range and feast on slugs all day, so lately not much duck food is being eaten anyway, but I'd like to have it worked out before they eat all the slugs! Okay in my yard, that could never happen, but I should work it out before winter It seems like lots of people are making and sprouting their own chicken feed - my neighbor says she's never bought commercial food for her chickies - and if our ducks are eating chicken feed anyway, it seems like we should be able to also!
