hi I am new. My girls are getting to 8 weeks old. I started them as layers but they are getting to become my pets, but I still need answers from people. They started running around our backyard when they were 4-5 weeks and I just moved them to the coop as of yesterday. I am confused about feed. We have starter feed, which I used when they were young to make sure they had no nutrient deficiency, but i also supplemented a lot of other food ever since they were very young, say 1-2 weeks, millets, sesame, corn grits, brown rice, oatmeal, fresh corn, grapes, eggs, nuts, tomatos etc. and they really don't eat that much of the starter feed. Here are my questions: What exactly are the ingredients in starter/grower/layer feed? Why do they contain the "complete" nutrients? If I let the girls run around our side yard, which is not very big, is that considered "free-ranging"? If they free-range (grass, bugs) and eat other whole foods (oatmeal, rice, vegetables), will they get enough nutrients or do they still need feeder food? People say chickens that are free-ranging and eating table scrapes do not lay as well, why is that? Thanks!
