How much nutritional yeast for chickens

[Rockergirl]

I purchased a bag of nutritional yeast for my 4 hens because I read it was good to add to their diet. However, I can't find anything that tells me how much I should give them? Is it a pinch daily, once a week, a certain measurement, etc? Any feedback from anyone on this? This is the one I purchased. Thank you.

Depends on what you are trying to do, and the value of the feed you are already offering. Nutritional yeast is a good source of Niacin (and many B vitamins generally) and is often added to duck rations for that reason. Its also a protein booster, good for molts. There can bee too much of a good thing.

After that, its simple math.

Beware generic "add this to their diet/water/etc" recommends. Much of the old wives tales are either just that - repeated through the generations because its been repeated through the generations - or hold a kernel of wisdom for some people in some situations. A situation you may, or may not, share with the people of ancient yore.

The poultry industry has done a lot of studies on yeast and yeast derivatives, and it definitely has an effect on immunity and intestinal health, as well as some other interesting areas like mitigating aflatoxin-which might be its most important use in the future.
