hi all. I posted a thread a couple hours ago about a duckling that was having troubles catching up to the other ducklings that I took in and it was doing okay, however I went to have dinner and when I came back an hour later the duckling was upside down on its back. and now whenever I put it upright it will just fall on its side, stretch its legs and turn its head upside down and face the other way. I will try to get some photos up

At least you tried for the baby. It’s a great time to add niacin supplement to your flock first aid! I would suspect nervous system issue (just so you can better prepare next time-Hopefully there won’t be a next time though.) I’m sure someone else will chime in and let you know more tips for your next duckling that has any kind of issue! Hopefully someone else can also pin point the issue head on so you know!! Once again, sorry for your loss
