This automatic feeder holds one pound of grit, aragonite calcium, or crushed oyster shells and will fill automatically as they eat. It mounts easily onto the head of a screw. It also features a cap that is easily removed, and drainage holes in the basin.
Chickens are able to regulate their own grit and calcium intake whenever these supplements are offered to them separately from their feed. Offering free choice grit and calcium supplements is an important part of supporting the health of laying hens.
