I built my first feeder last week. After we ran out of feed in the can, we switched over to the feeder. I guess I didn't realize how big I made it I thought I made it too small because I made the inside of it quite a bit smaller by adding reenforcement pieces. Well, we poured a 40-50 lb. bag of feed in it and it didn't even fill half of the feeder But it works like a charm. There's already less waste and more room in the coop without all of those darn mini troughs! My question though is, how much feed can I actually keep in it without it going bad? Does it go bad? I dunno... All I know is, this thing could hold a good 150 lbs. of feed. Can I fill it or is that not a good idea? Any ideas about bugs? <--that's my Mother's biggest worry but I don't think it will be a problem since it's sealed up pretty tight. I need genius brains!!
