Duck feeder

[whiskey69169]

I just got 4 pekin ducks 1 week old. I own chickens and have a set of these already (just getting into ducks also), but want to know if these will work when the ducks are older on their feeder?

That will be too small for adult Pekins.
May I suggest a cheap & scalable solution to build one of these, I have and I love it:
