I just finished reading what seemed to be a bajillion mix-your-own-chicken-feed recipes and rules. Ingredients range from black sunflower seeds to a bunch of other things that I would feel very UN-self-sufficient if I had to hunt it all down at specialty mills, etc. Does it REALLY need to be that complicated? I have read that our ancestors often free-ranged their chickens, fed them extra random grains from their own supplies (and kitchen scraps), and crushed up egg shells and put them in the feed for extra calcium. If many of our ancestors and their chickens survived well with these types of simplified methods, why can't we? Have chickens changed so much over the last several decades?
