Discoloured yellow drake! Need advice ASAP!! X

[cheezenkwackers]

My young full grown Pekin Drake is yellow as well! He was hatched with a niacin deficiency and I thought it had something to do with that possibly. I brought him in and hand feed him and babies him until he walked on his own. Now he is out with the girls! Does anybody know why is he yellow? All my other pecin ducks are white!

How did you baby him? Did you give him b vitamin complex? If so, the b vitamins include beta carotene which is the yellow color.
