I just got back from the feed store where I was picking up some chick starter for my chickens. They are about 9 weeks old and I have been giving them the starter plus greens and scraps. All they had was (manna-pro) game/show feed and they said it is basically the same thing and fine for them to eat. Is this true? If they need to be older for it I will just hang on to it and pick up the starter feed somewhere else in town. What do you think?
