I've been driving myself crazy(er) trying to research grain/feed storage options for someone who goes through as much feed as I do (more than someone with 3 chickens, way way less than someone with 300,000 chickens).
I came across a product today ... a "bear tight" garbage can from Home Depot. The video made me giggle, so I looked it up on YouTube.
Oh wont someone please give that poor frustrated bear a cookie! Ha! Loved the video.
