IMO 'The Best Feed" is really almost all personal preference and opinion for most...
I have always been of the opinion that man created 'balanced diet all purpose feed' is never a total replacement for a varied diet...
Now don't get me wrong, lots of scientific study has went into discovering what each animal needs and most commercial feed is tailored to those studies and no doubt animals can survive and even sometimes thrive on many of the commercial feeds as their sole ration, but most will agree if you really want the birds to thrive it's generally best to add something more...
For that reason for me the cheapest and closest proximity commercial 18% or greater (non-layer) commercial pelleted poultry feed is the BEST I supplement heavily with an ever changing daily offering of fresh produce (and sometimes scratch) that is dusted with a fermented yeast/grain feed additive, to me this provides the best of both worlds as they have a never ending supply of a higher protein 'core' diet from the pellets and they get the varied diet by the supplemented foods... And this doesn't break my pocket book as the fresh produce I get is pulled from the shelf 'imperfect' or 'day old' from a few local ma/pa grocery stores for free...
