I don't know about that Jaku, aren't you the one who just lost 27 birds to what sounds like a mix up at the feed mill? I pay a little more for the Purina, but have the peace of mind of consistency. Plus I can buy a 50# bag whenever I need it, for me that's much more convenient to my lifestyle and storage availability. I would like to get my own feed ground, and am experimenting with supplementing with whole grains, but lacking a degree in animal nutrition I decided to leave that up to the experts for now.
