How to tell if ducks are underweight?

[Isaac 0]

Some brewer's yeast brands contain very little niacin, so you may check your brand. On a general basis, most ducks under eight weeks of age should have around 55mg of niacin per kg of feed. Pekins and other heavyweight breeds grow at a faster rate and should have around 70mg of niacin per kilo until they are eight weeks, then you can feed a 55mg/kg feed.

You can contact the company and ask their niacin content if it's not listed on the bag. I'm under the impression most are 55mg/kg besides Mazuri-type feeds.

I don’t remember the exact brand but it starts with a H... I’m going to check in a bit!
