We have two small metal trash cans that we keep in each coop. One holds feed and the other has scratch. We pour it straight into the can (no bag), and we can fit most of a bag in a can. We usually just set the remainder of the bag on the floor beside the can. We've never had a problem with mice, because the food is in the coop, and our girls will kill the mice. We also keep two full sized metal trash cans in our barn where we store extra bags of feed, dog & cat food, and birdseed.
