So, I am new at this obviously! I asked the local farm feed store what to feed my ducks they told me medicated starter that is what they fed their ducks they sold. Now I am realizing the mistake, I have 3 pekin, 2 runners and an unknown. I mixed them with my chickens which has worked out ok, Yes ducks are horribly messy and they definately hog the water though. I fed the medicated feed for 6-8 weeks then stopped and moved to reg feed. The ducks seem healthy but what can i give them to help correct the problem. Vitamins? or just stick with the feed? Any ideas to help me? Thank You
