Meat bird feed for starter grower

[Swiftbug2]

Gonna be hatching a clutch of barnyard mix (layers and dual purpose breeds) soon and was looking at what feed I wanna go with. $20+ per 50lbs starter grower is a bit much imo.
Was wanting to know yalls thoughts on using a meat bird feed as a starter grower. Local feed mill has it for around $11.50/50 lbs

Specs on the feed are
Protein 22.1%
Fat 3%
Max fiber 3.1%

The dumor starter at TSC
Protein 20%
Fat 2.5%
Max fiber 4.5%

I raise silkies. To me, that would be great as they actually need a bit higher protein than most other breeds.

I raise my DP birds on a local mill's 24% "game bird" feed. Would like to see more than just crude protein, like key aminos- but your top line numbers look good. Should work for you.
