Feeding plan for mixed flock of 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 feed mine purina start n grow for the first few weeks, until they start to feather out pretty well, then I start feeding them flock raiser until they are grown and show they are getting ready to lay, then I start blending their feed to whatever they will be eating as adults. I try to get them weaned off the baby food before they lay.
