I get this at the pet feed store, our local pet "mart, smart co" doesn't sell this large of a bag, so I go to the feed store in the neighboring town. It lasts me all year with several types of birds. I usually stop by the butcher get ten pounds of suet (fat). I take an onion bag, two pounds of suet roll the suet into the bird feed, put that ball into the onion bag and hand it from any tree but make sue the temps stay under 75 for the suet doesn't melt. Summer time I put a bowl of it in the middle of bird baths or in bird houses in the trees.
