I feed my grown up ducks the »Meatbird Crumbles« from the local farm-store, some cracked corn and treats like meal-worms, kale, (iceberg) lettuce, tomatoes, … .
Those crumbles are for chickens, but the ducks are doing fine with them. The same here, during the warm months they stay almost untouched in the feeder as the duckies are foraging for insects and weeds (they are really good in weeding out those pesky tomato plants…). My ducks hate scratch grain! They pick out the Corn and throw the remaining grains all over the place, i use the scratch grain now to fill up the bird-houses…
So, Chicken Food plus treats to provide some extra protein is sufficient for grown up ducks.
But its a different story for ducklings! They need way more protein and Vitamins than what is provided in Chicken Mixes. I was lucky to secure two bags of this:
At my local farm store for my Spring Ducklings. They carry this stuff only in spring. Ducklings need protein, protein and protein to grow super fast. Maybe Chicken Food plus ground up meal-worms would be an option in the Netherlands. Or Crumbled eggs?
For the vitamins, especially Niacin, i have ordered 200 grams of Niacin at Bulksupplements.com - i don't know if they deliver to Europe. But it is available on eBay.de (Is there an eBay.nl?): https://www.ebay.de/itm/NIACIN-Nico...ab7d1e8ab:m:mEKfpFWmccTbQZeSD5c1oSQ:rk:1:pf:0
Don't you have farm stores in Holland?
The 2 TSC by me carry duck stuff and duckling stuff all year round. I took that for granted!
