My general recommend, for the typical backyard owner, of the typical backyard flock, with typical backyard management is that they feed an All Flock/Flock Raiser-type feed to all their birds all their lives, without regard to age, gender, laying-status, or molting status. Together with Oyster Shell and Grit in seperate dishes, free choice.
All Flock/Flock-raiser type defined as an 18-20% protein feed, about 3.5% fat +/-, about 3.5% fiber +/-, about 1.5% calcium +/- (in ddecreasing order of importance).
Crumbles are best if you have chicks, of course. Pellets are fine to control waste if all your birds are larger. Making a wet mash of it is just fine, as is fermenting. Straight out of the bag is fine too.
Full Disclosure - this is not how I feed my birds, but I have neither the typical flock, nor the typical management, and am better able to judge the risks and benefits of an alternative diet than most.
