I am considering getting some Cornish Cross Chicks because the local Rural King which JUST opened up is selling them in store. (That's how they're advertised!) IF I decide to buy, it's gonna be fast, in the next day or two. What should buy to feed them? They're advertised as "fast developing--ready to dress in 6 weeks." Should I feed them Chick Starter, or should I feed them feed for meat birds? I'm inclined to get a bag of Chick Starter. My other birds are now on Layer feed and I used up their baby chick food.
