some of us, myself included, have strongly hinted that if the extent of one's knowledge of poultry nutrition comes from a Mike Adams video, a teenage YouTuber who can't do algebra, or a tick tock video shared on Facebook, that one lacks the necessary knowledge base to make feed effectively for the health of your chickens. The vast majority of recipes being tossed around can't even accurately report their crude protein levels. If they can't get that one claim correct, why should any educated person assume they accidentally got fat fiber useful energy calcium phosphorus iron selenium a host of water soluble and fat soluble vitamins and a number of trace minerals correct, to say nothing of an efficient amino acid profile, and a a minimal level of anti-nutrative factors to compensate for?
