After my six chicks were a week old and doing well with no eating and drinking issues, I started giving one hard boiled egg with some greens/veggies and grain/seeds I mentioned above every day in addition to 20% chick starter. My chicks didn't like the veggies cooked, so it was a few days before they ate much of it. Divided between six chicks, they still didn't get enough to keep them from eating a lot of the chick feed. Most of the nutrition needs to come from a balanced starter feed, with the treats as a supplement. Many people feed bread and white flour treats like cooked spaghetti noodles. I never did that because white flour products are nearly void of nutrition and are very filling. If you do feed noodles, do it just for the entertainment value of chick keep-away, and don't feed it to them often at all.
