I'm almost out of my game bird starter feed. I have a LOT of chick starter that is medicated for coccidiosis. I know that I've read that medicated feed is a huge no-no for ducklings. Why is that? I know. My bad for not getting more feed for my duckling kiddos before Sunday when the feed store is closed. Lesson learned. What else can I give them in a pinch should they empty their feeder today???? Thanks so much guys. I'm new to ducklings now that I've semi-matered chickens. You guys rock!
