When to move to grower/finisher?

[amshizzle]

I have two Pekin ducks that turned 3 weeks on Tuesday.
I currently feed them Dumor chick starter/grower (20% protein) with added Brewer's Yeast.
They seem to be growing like weeds and are messy (and sometimes rude) but so adorable!
When do I move them to grower/finisher (15% protein)?
The back of the bag suggests 10 weeks but I have heard so many people say 2 or 3 weeks... .which means now!
Any suggestions?

Your feed bag should have feeding instructions on it.
The manufacturer knows what it was formulated for and when to switch.

If the bag says 10 weeks, that may be for chickens but if for ducks as well, follow the instructions.

I hope the following chart helps.

I switched from starter to grower between 2 and 3 weeks, adding at first a little grower to the starter and increasing the grower till the starter was used up. That was based on Storey's Guide to Raising Ducks. I would keep up with the Brewer's Yeast for another 6 weeks or so.

@amiga did you add grit to the grower?or is that only needed for anything other than chick feed?

I added a tiny tiny sprinkle once a day to the feed, per Storey's Guide to Raising Ducks, till they were going outside and foraging and picking up grit for themselves.

Some feeds have sand in them for grit, I have since learned. So check the label.
