Duckling feed

hello
I have 4 10 day old ducks which have been on starter crumb for waterfowl. I have got through 3kg in 10 days. How long do they stay on started crumbs before moving onto grower?

I started switching my runners over at two weeks. I added a bit of grower to the crumbles - first day, 1 part grower 5 parts crumbles, second day a little more grower, a little less crumble. Once I got to about 5 parts grower and 1 part crumble, I stayed with that till I used up all the rest of the crumble.

Took about a week or so if I recall correctly.
