I've heard good things about Blue Seal foods, although they're not readily available here near me.
The standard here is Purina lines. But I have used some Nutrena poultry/game feeds that I felt were exceptional! In fact, I had started some chicks on a locally milled starter, MG, which I hate honestly. I switched them to a Nutrena game starter (because I had goslings, poults, and chicks all at once in separate areas of course) and I was amazed! It smelled so beautiful - fresh, very strongly of fresh ingredients. The crumble size was lovely, easy for them to eat, and slightly larger so you have less nutrient loss. The chicks feathered out beautifully!
Because the feedstore that sold it was a little far, I switched back to MG during the grower stage and after two weeks I realize it was a mistake. I'm going to make the drive for the Nutrena because it was lovely.
I've raised some show birds before (before raccoons judged that they were the tastiest) and am about to restart a show line. I was lucky enough to get two birds ribbons in nationals, and I hope to again. But I didn't have the advantage of this feed now. I sure will be using it on my new breeders and chicks.
Boy, do I sound likea commercial for them or what? HA! Seriously - I'm ultra ULTRA picky about feed. And this one bowled me over.
OK, my happy-rant is over.
