If these are Ducklings, Purina has out a Duck Starter mash that is for Ducklings, Don't matter if they are Wild Style or Tame Ducks.
After about 3-4 weeks switch to purina's Duck Grower and add in the lettuce, Corn, Popcorn, wheat, Millet, Milo, Cracked Corn, Sunflower seeds, Peanuts.
Mix it together and feed it to them!
Looks like there was aLOT of Ducklings Sold for Easter, from the posts on the site.
