chick starter is all they need. the other stuff can give them runs. i grind in food proccessr when young(2-3 weeks) give starter till fully feathered. then u can give snacks.
my rir's took 25 weeks. now i get an egg a day. sometimes i wish they would stop for a day or two. so i can get caught up eating the eggs.7 eggs a day is alot for 1 person. lol
