So I don’t need to add the yeast ?
nope, duckling feed is made for ducklings so has everything they need. chicken feed is not for ducks which is why u need to add all the extra stuff when u give them it
What is the best to recommend? Is brewers or nutritional yeast better ? Also does it hurt them if I put that amount once a week or no ?Sometimes even when feeding a duck formulated feed you can still have one that will come up with a niacin def. could be they aren't assimilating the niacin properly and they can still show up with lameness or they well begin to have pigeon toes or bow-legged. So always be prepared to treat ASAP to get them over it quick. Best to have on hand some liquid B Complex if to the point you notice something not right, and just to be on the safe side have Nutritional yeast to sprinkle over their feed at 1 Tab per cup until at least 10 weeks of age, What they don't need they will get rid of thru their kidneys, Pekins are notorious for having leg issues they grow so fast,
