I Store my chicken feed outside in aluminum garbage cans with lids. I had to throw one bag away bc the lid wasn't tight enough and water got in. The second one has a super tight lid so no water but I just discovered worms all in the feed as I got towards the bottom of the bag. Probably maggots, Tanish short fat worms. I'm tossing the food but think the chickens ate some of the worms. Is this ok? Any suggestions for better food storage outside? Hate always having the food go bad??
