Joe, I completely agree with the "total package" concept and you know lots of folks would say we are nuts but that's okay, too!
As far as feeding Buckeye chicks my formula is pretty simple, feed a 22-24% chick starter that has ANIMAL PROTEIN and feed it to them until they are 4-6 months old. While Buckeyes benefit from higher protein to help build muscle and bone they certainly don't need to fed like turkey's! The biggest issue I see in commercial feeds today is the trend to go 100% plant protein and to me that is a huge mistake. If your label does not say "animal protein" then you need to add fish meal or fish pellets to the mixture. In addition to feeding a good "chick starter/grower" I believe adding an electrolyte with extra vitamins and minerals into their water every couple weeks is a good idea, too. When they get older and are running outdoors I like to add some whole corn and a little BOSS to their diet but not in huge amounts and never in extremely hot weather!
That's just me and how I have done it for over 12 years now and my Buckeyes grow well and meet standard weights at relatively young ages compared to others that are fed lesser quality feed.
