My chicks are 9 weeks old and I am almost done with a bag of chick food, I don't want to buy another since it only comes in 50lb bags. I am told at 11 weeks I can give them regular chicken feed. But for the time being can I get another brand that comes in a smaller bag? I have been feeding them organic feed. They eat dried crickets whole. LOL I also realize that the chick food is needed for their growth. That being said any input is appreciated from me and the Australorp Gang!
