My ducklings aren't eating.

My ducklings aren't eating their starter feed. Before i had them on that, they ate koi food for 2 days, now thats the only thing they will eat, so i try mixing it together and they still wont eat it, mixed dry and wet. The only time they will eat is when i sprinkle the koi food on top of the water bowl. Please help me figure out a way for them to eat their new food, any healthy treats that they love i can get them ? Theyre a week and 6 days old, i want to start them out healthy and this is not helping...):

Hmmm, ducks sure can run us around with food choices sometimes.

Do they have food and water 24/7?

What brand are you feeding them ? Crumbles or pellets?

See if they will eat a few thawed frozen green peas. Just a few. I forgot how many and what kind of ducks you have.
