They will need a tablespoon to each cup of feed you give them . nutritional yeast in tablets would be fine if you want to go that route and crush them or buy the now brand flakes decide on which is more responsibly priced. Both will work
If you go for pills just crush and flakes would still be 1 Tablespoon per each cup of feed until 12 weeks. Many here who have Pekins give them Nutritional yeast all their lives since they are prone to leg weakness from being a heavy duck breed.
