The hay holder below will hold hay cubes and loose hay.
It easily made with a little bit of wire,
C clamps and a hanger/closing hook.
You leave the last side connected by one side only, to make your "top" to the feeder.
It's best to hook your last piece together with the hook it will hang on. on the side that opens.
You can make the the size you want ... I usually do a 2" square for single chins and a 4" square for pairs.
These can be made with 1" x 1" wire, or 1/2" x 1" wire, or 1/2" x 1/2" wire.
The 1/2 x 1 seems to work the best ... easy to get the loose hay out, but not so easy that you find allot of it falling out.
