Ok, so I have had my feed in a few different things. First, I tried food grade buckets. I could only find 5 gallon buckets, which doesn't hold a lot of feed and puts me in a bind of what to do with the rest of the feed in bags. Plus, it was really hard to get the lids off those buckets, and as a twice a day thing, soon became quite tedius. Then I tried plastic bird seed container. I believe it was a ten gallon container, which was NOT air tight and allowed spiders to get in it! Then, a mouse or some kind of rodent chewed the lid, so that was the end of that. Now, I am using a metal bird seed container with a lid. You can get it at tractor supply, and I believe it is 20 gallons. However well it works for rodents, moths have invaded my feed! I put some food grade diatemacious earth in it, and although I do not see any more moths, there is still those stringy, spider web type things in my mash feed. This was expensive organic mash, so I am continuing to feed as I read that moths wont hurt. With winter coming up, it soon will not be a problems, but how do you guys keep bugs from your feed?! Moths have also invaded my BOSS, wheat, and scratch mix that I left in bags on high shelves in my RV hanger. Someone help me, please!
