Feeding plan for 5 chickens and 2 pekin ducks

[IRL]

Hi!
I'm planning on purchasing my first few birds next month. The flock will hopefully consist of 3 buff orpingtons, 2 barred rocks, and 2 pekin ducks.
I'm hoping to feed the ducklings and chickens dumor chick starter/grower, and the move on to a mix of purina layena and purina flock raiser when they are older. Does this sound like a decent diet, or do you have any recommendations of a better combination of feed for a mixed flock. Thanks for your help!
(I think I will post this in the Duck sub-category as well)

Just make sure that you use the NON medicated chick starter. Ducks can't have the medicated kind. You can also use Flock Raiser on both birds from the very beginning.
