I have three muscovy ducklings that are almost 4 weeks old today. One of the little ducklings is about 1/3 of the size of the other two, maybe even smaller! At 4 weeks old, it still looks like a little baby not much bigger than one hatched a few days ago. It has had a couple strange issues since it hatched. When I first put it in the brooder, I noticed a fairly loud grinding sound like it was chewing on rocks. A couple days later it went away. Then about a week later, the duckling seemed to sound almost congested in it's beak, not it's lungs, so I separated it. It eats regularly, but not a whole lot, about the same as a duckling his size, but not his age, wet and dry food and fresh water available at all times. The congestion stays away, but it cleans its beak out more than its siblings do. It likes this one certain small bowl, and if I use anything else the congestion sound seems to return. It has to be just barely tall enough to clean its beak, but any taller and then it will only drink and not flush out its nostrils. The duckling is active and wants attention and loves its siblings even though I don't let them stay together, because it is so small and I was worried it might be sick. It doesn't act sick. It acts fairly normal other than it rinses its beak out twice as much as everyone else does. I have been adding extra niacin and baby vitamins to the wet food, and put a tiny bit of apple cider vinegar in the water about half the time. I have been feeding him some ground up high quality dry meal worms for a little boost a couple
times a week, and he still has a brooder heater to climb under. I am sort of at a loss for what might be wrong or what to do. The biggest issue is it just isn't growing. It definitely is not declining. It is exactly as active and runs around the same as it has from day one. If anyone has any ideas please let me know! You can tell he looks small in the picture, but he looks even smaller in person. I don't know if this is important or not, but they all hatched one day apart from each other. The little guy was breech and the last to hatch on day 37, and all of them needed a little help. Humidity may have been too high during incubation, and I had a little incubator miss-hap where the eggs got way too cold one night at about 2 weeks into incubation. I lost a couple egg babies from that incubator, but the majority of them, and all of the ones in the second incubator hatched perfect! I will attach a picture of some of the other pretties who hatched about 2 weeks before my muscovy. They are almost fully feathered and so pretty I think! If anyone know what might be wrong with my little muscovy please let me know what I should do. There are absolutely no vets even close to our area who will see birds. We have a vet about an hour away who will do post mortem exams, but no one to help with live babies! This is my first thread ever, even though I have been following for a while now. I didn't really see a Muscvoy specific thread that matched with my question. Please someone let me know if I did anything incorrectly or something that I am not supposed to! Thanks!
