I plan to store my 50 lb feed bag in a 31 gallon galvanized trash can with lid. The pail will be place inside my garage. I have dear, raccoons, occasional mice and very few (visible that is ) snakes in the area. My 8 chickens will consume about 55 lbs. per month. Is this a proper storage procedure? Should I use plastic as I read that galvanized sweats (condenses) and may contaminate the feed with mold? Should I use a 20 gallon pail or will that not be enough for 50 lbs.of feed? I am looking for your experience and practical advise.Thank you for your help.
