I’ve never raised ducks before but recently rescued 4 a week ago. From my research they appear to be 5 weeks old. Three of them are doing great but the feet on one of them are curling in. He does not stand up and when moving shoves his beak down to help scoot forward with his legs. I also noticed for the first time today that he took a few steps on his hock joints. He appears to be eating and drinking well and enjoyed some time in shallow water yesterday. From research i have done i am currently mixing 2 niacin tablets 500mg per 1 cup of food. Yesterday i also picked up Maxi-B 1000 and gave 1mL orally (I was unable to find vitamin B complex) any tips or advice to please help!!! Also has anyone seen a duck recover from looking like this and will he be able to have a good life?
