I am preparing for my new chicks, and trying to make some decisions about what I wil feed them. I'd like them to eat as healthfully as possible, and as close to a "whole food" diet as possible, while meeting all their nutritional needs. There seems to be the standard diet of crumbles, pellets, scratch, kitchen scraps, etc., and I am wondering what other regiminies or feeding options are out there? Are there specifically "organic" brands of feed, or is there some kind of whole food chicken diet? Thanks!
