I have read several times that people recommended cat or dog food for their ducks. I have never fed it to our, but was just wondering under what circumstances it is warranted? A treat? Cold weather? Sick ducks? I'd hate to miss out on giving our drake and ducks something that they should be having. We feed peas, cabbage, Blue Seal Grower Cal, oyster shell, occasional chopped veggies, and whatever they can find to free range on. Am I missing something important? My ducks seem healthy. And happy.
