Ok this has prolly already been answered but I need help. I bought some cornish cross for my daughter at Oscheln's. I bought thier game bird starter that is 22% feed. The I realized that Purina game bird starter is 30% feed. Which should I buy? The Purina at 30% or the Country Lane at 22%. These birds are for a 4H fair & will be shown July 22-23. I can buy the 2 feeds & mix them if that is better. I thought I had seen somewhere that a 26% feed was best. I am confused & just need to help educate my daughter also. I will be her poultry leader next year & really have been for the past 2 years even though someone else has been her official leader. Thank you for your help.
