Duckling to duck feed change

[Autumn B]

So the place we got our ducks from suggested we start our ducklings off with chick feed. Well they are getting so big, I was wondering if there is a time im suppose to get them to start eating more mature duck feed, like pellets, or if they are fine eating the chick feed.
