I Have runner ducklings and cayuga ducklings that I ordered and they will be here on Wednesday. I have searched and searched and the only thing that I can find without special ordering feed is purina startena game bird starter for growth and plumage. The stores near me do not carry anything specific to starting waterfowl. is this food okay? Should I need to add brewers yeast for the niacin? These are my first ducklings I have the my brooder and heat lamp and pine bedding, feeders and waterers. I may just be overly worried and making things harder then they are. I have read and Keep going back to my copy of Storey's Guide to: raising ducks. I keep it handy and I have niacin on hand. I just want to make sure this is a good feed that I can use as nothing else is really available. Thanks for any advice that you can give, I am exited I have taken days off work to pick up my babies and start this journey.
