I have some ducklings due this Wed. I can't find any food around here that is not medicated. One place has the Dumor Starter/Grower. It has a chick and duck picture on the front and no mention of medication. The lady at the store told me today that it does have something in it. Some sort of medication. The bag is yellow. She said I could use chick crumbles. What can I use to fee the ducklings when they are born?
