I sent my daughter to pick up starter/grower from the local Feed store. We've always picked up Purina from there. This time they loaded the feed as usual, she drove 20 min home, and found they had given her Kalmbach Feed from Sandusky, OH instead of our usual Purina start and grow feed. Any one use the Kalmbach brand before. I only have a couple days of feed left and don't really relish the trip out to exchange the feed. Our chicks are 3 at 15 weeks, 7 at 10 weeks, and 5 at 7 weeks. Think it's ok to feed Kalmbach starter grower for game birds?
