I can’t wait until my 11 week old chicks are big enough to free range. Probably soon because they’re growing fast, but in addition to chick crumbles I offer them armloads of all different weeds and they love when they see me coming.Chickens are omnivores and left to their own devices will eat a wide variety of vegetatable and animal products. They'll eat frutis, tender greens, nuts, seeds and any vertebrates and nonvertebrates they can swallow. They are diven by hunger when the crop is empty. They are driven by the need for energy and protein. Extensive research has identified a long list of vitamins, minerals, amino acids and fats that chickens need and in what ratios at specific ages. A complete feed free choice and good forage is best. Most people don't have the appropriate amount of forage available to keep modern chickens healthy. Chickens don't eat or drink at night so it is only necessary to provide those things after daylight.
