In a pinch you are fine, but make sure you supply niacin. Smashed peas is a good source or you can buy vitamins to mix in the water. Niacin deficiency can cause a lot of problems for ducks, especially ducklings.Duck friends, can I feed a baby duck chick starter in a pinch? A neighbor found a single duckling in their yard and no mama nearby. They posted in our neighborhood FB group asking if anyone has seen mom or knows where this baby came from but it looks like it's only a few days old -- maybe a week? If she can't find the rest of the family soon, I wanted to walk over some chick starter just to get the little bit something to eat. I'm likely the only one in the neighborhood with anything even close. Unless we have someone with ducks who lost one! LOL!!
