Because of my small flock and limited coop space, I wanted to use a hopper style feeder for my birds. I'm having trouble finding one (yes, I did see one member's plans for building one, but after many hours of coop construction I can't give my husband another task!) Think that this grit feeder would work? It seems to be the perfect design for me - other than capacity being a bit small. I imagine I would be filling it nearly every day. http://www.nepigeonsupplies.com/images/cart/0789 grit_hopper.JPG The most annoying thing is that tons of what Im looking for seem to be available in the UK. The US just doesn't feed their birds with this type of setup!!
