My duck isn’t walking and is not eating much

[Eliezer81727]

Basically my duck is stuck in the same place he’s not walking and when he tries to he falls like he’s weak I try giving him food and he just munches on and then spits it out he’s just drinking water and his beak is turning kinda pink and warm.

Can you please give us more info? what breed, what age, what do you feed? and How long has this been going on? Are you using any supplements and has your duck ever been on niacin to help build leg strength?
