Best food for 4 month old ducks?

[Iamgrateful]

What would be a better option for my 4 month old Pekins?

Purina Flock Raiser or "Duck Pellets" (sold at the feed store).

Are the duck pellets made at the store? Wondering if you can find an ingredients list.

Many people on the forums like the Flock Raiser.

I use Blue Seal Organic, plus some extras depending on the season.
