Duckling Food - enough niacin?

[Brittanyyy]

Hi there!
I’ve had two ducklings hatch in the past few days and I am wondering if the food I got has enough niacin? It’s mannapro duckling and gosling starter grower. I’ll post a picture of the label. It says 35mg/lb.
These little babies have brought me so much joy (and stress from worrying) in these past few days. I had someone lined up to take them but they have backed out. I would love to keep them but I just don’t think I have the right yard or setup. hoping to find a loving home for them soon but want to make sure they stay healthy and happy in the meantime.
Anymore advice would be great! Thanks!

Here is the label

You don't need anything fancy to keep ducks just a secure house for nighttime and fencing to keep out most predators during the day,
Your food looks great and since it's formulated for ducklings and goslings it should be fine. If they are Pekins then you might want to be ready in case they should need some extra Nutritional yeast since the heavier breeds especially Pekins can end up with a niacin deficiency even if they are one the right feed.

Awesome thank you!
I live in NH, do I need anything special for the winter?
I believe one duck is a Cayuga and I’m not sure about the other one... possibly a mallard?
