OK, I order my chicken feed from Countryside Natural in Virginia and they ship it in a heavy brown paper sack inside of a brown box. I want to put the food inside a plastic kitty litter bucket and my mother says the food needs air or it will go bad. What is your opinion? I am afraid of keeping it in the paper bag/box because of mice....but Mom insists that the kitty litter plastic bucket will spoil the food much quicker. Common sense told me to post my question here .... So Paper or Plastic??
