I bought 200 pounds of Purina Flock Raiser the other day. Last night I opened it, and it was spoiled. It was clumped and moldy. The bags looked fine, so I assume it was packaged wet. The feed store will take it back and order more. I only buy that brand because I have the coupons from poultry press. The feed dealer isn't that close by, so now I will have no savings at all because of the gas it will take to return the garbage. Has anybody else had a problem with purina?
