I give all my ducks the right protein feed, the good niacin supplement for their water, and give peas daily to help. All my other ducks are fine but my Pekin boy Snow is getting worse. I don’t want to give up on him. He barley walks, he stumbles, uses his beak to push on the ground to help get his body up, his legs are shaky. He sits most of the day, and he can’t keep up with the other ducks. He seems stressed all the time. He can’t run or nothing. Today he has gotten worse. I have to help him every day with eating and drinking. I’m afraid he’s living life in pain. What else can I do for him? I’ve tried giving him extra niacin and it doesn’t help him, what else could this be?
