We're limited to feed available here, Dels sell limited TSC supplies and Miranda's sell limited Nutrena. Land 'O Lakes/Purina manufacture alot of feed under different names. I've now feed Purina Flock Raiser (fermented) love the results.
When I first started chickens, I was sold Home Grown which was ok but then it was unavailable and was sold Dumor ... Will not recommend Dumor. I found the poop was dark in color and stunk so bad, even when fermented. I then did alot of reading (BYC) and switched to Flock Raiser, pricey but I love the results.

I've considered switching to Nutrena, waiting to see Kiki's results. I may with my next round of chicks in July.
