Hi all. My birds are 15 weeks old. I had them on a local mill's grower feed with 18% protein. I changed because there was a lot of powder in the feed that they were not eating. I decided to try Purina Flock Raiser. They like it fine. In fact they are eating a lot more of it. Am I right to assume they are only eating what they need, and so they need more of this feed for the same nutrition?
