My feed store carries very small amounts of everything. I'm in the city and there aren't tons of chicken owners. They usually have about three bags of each item. Anyway, they're out of "chick starter" feed and so I got a bag of "chicken scratch." (I think that they buy in bulk because chicken feed is sold in brown paper bags with the contents written in sharpie--no ingredient lists or explanation other than that. My three week old and five week old chicks are totally uninterested in the scratch and only want the starter. Should I keep offering both and for how long? I am giving them access to gravel mixed in with other feed as well. I'm going to go get more starter feed as soon as they get it in and still have some to tide them over. They act very hungry when I get home and go to bring them starter even though they'll have full feeders of the scratch. Are they just too young for it yet?
