That is similar to what I've been doing lately.
Flock raiser (crumble) in the feeder. Nutrena all flock pellets (mixed with a small amount of scratch) as the primary treat to toss in the run.
I can only tell you how I did. Flock raiser from cradle to grave. Short of that, starter/grower. Oyster shell on the side,of course. Took me a little minute to settle on flock raiser, but I'm not looking back.
