Please help! My girls are very messy eaters - I only have 3 hens and they can't keep their feed container full for more than an hour without spilling it everywhere. I just went out a few minutes ago to see that they had completely destroyed the feeder - it's in 3 parts now. Since I use organic feed, it just about kills me to see it all over the ground where they ignore it. I have this type of feeder now http://www.mypetchicken.com/Feed_and_Feed_Supplies-3lb_Hanging_Chick_Feeder-P387.aspx They managed to unscrew the nut at the bottom and it all fell apart. Does anyone have any suggestions for a spill free feeder? Thanks!
