Need help with duckling diet

[DramaticDucks]

I was wondering if feeding you can feed 4 week old call duckling cooked rice and sometimes millet, green peas, corn, eggs and kidney beans as their main diet?
Because I can’t find any duckling feed or brewers yeast.
If there’s not enough of vitamins B can I add some crushed human vitamins?

You cannot replicate all they need. Go on line and look at recipes for making feed.
Can you get all flock? All flock would be better. And yes you can use human B vitamins Just make sure the niacin isn't time released or flush free.
