Well, this new chicken raising addiction of mine has put me in a situation. Got my first batch of silkies chicks on march 16, added one 2 day old RIR more a week later, two weeks after that found a 2 week old BO to toss in the brooder, and now I just tossed another 2-3week old BR to the mix. Then I realized the younger ones are suppose to be eating different feed. So how different are grow vs starter? I dont want to separate them as they all get along so well, and right now they are eating grow. But whats in starter that the younger ones aren't getting or whats in grow that could be bad for the younguns?
