I went to great lengths to get unmedicated chick starter for my chicks, because I had heard that ducklings should not have medicated chick starter and I didn't want any around in case my future ducklings got ahold of it. Now, when I need to get more chick starter, my car breaks down and it may be a couple of weeks before I can get it going again. Unfortunately, the only places that are close to me sell medicated chick starter and my ducklings are being shipped next week. The feed store guy said that they get ducklings in "all the time" and feed them the same as the chicks. Should I believe him or should I call the hatchery and see if I can cancel/move my order?
