My little duckling is 4 days old and all of a sudden, has trouble balancing and walking on one foot. I’ve been feeding my 4 ducklings DuMor 22% Duck feed with 35mg/lb of niacin. Is this sufficient? I plan to switch to a lower protein level at 2 weeks. I’ve tried getting him to eat and drink but he’s not interested. Added supplemental nutritional yeast to the water and food but not interested. What do I do? I have a couple of Tractor Supplies nearby but not sure what to get him. Please advise! Thank you.
