Wow, look at all these chicks!! Congrats to your mama duck as well with her babies :celebrateSo sorry that Ducky didn’t develop, and that Dinky didn’t make it :hugs It’s a part of hatching, unfortunately. You’ve done a great job so far. I wish good luck to the rest of your eggs.
My ducklings get Purina’s duck feed + ~1 tbsp of nutritional yeast per cup of feed. Purina has niacin in it already, but I give the extra niacin just in case 😂 It’s been great for my adult ducks, too. No clue if it’s good for Muscovy or not.
