I have a 7 week old chick and I'm thinking the two new chicks I got are just a hair younger. Probably 6-7 weeks. They still have fuzzies on their heads but it's almost gone. I also have a bantam rooster who is young yet (just started crowing) and I just got him. They are all eating Dumor chick starter. I give them chick grit also but they get to run in the grass all day in the little coop I got at tractor supply. I haven't given them too many table scraps just yet. What do I feed them next and when? Grower? Now?
