I have 5 pullets and when they were chicks I bought 5lb. chick starter bags...but now that they will be on developer/grower for a while I bought a 50 lb. bag. I stored it in a plastic container but when I went to replenish the feeder..little moth like things were all over the place...so i transferred whatever i had to those huge oversized ziploc bags...when i went to replenish the feeder there was like 1 of the moth like things..so definately better then the plastic bin..but what would be ideal for storing the food??
