I have decided to try and make my own duck food. I make food for my dogs, so why not. I have been looking on the internet and not piling up to much. I really don't want it to be chalked full of fillers, I am looking for something really nutritionally beneficial to the ducks. Both of my ducks are pekins, and getting a little chunky from their current feed. My drake is about 6 months and my female 4-5 months. My ducks free range all day, and get feeder fish about once a week. I was thinking about purée and mix of different fruits and veggies, with some corn meal, and eggs, also adding some vitamins and minerals supplements I have, and a little grit. Also I would add some yogurt for good probiotics and calcium. Then making like little frozen pieces I could defrost for feed. Does this sound right, or am I missing something essential? Any suggestions or ideas would be helpful.
