Feeding Directions
Purina® Oyster Shell provides supplemental calcium in situations where the fortified layer diet may be diluted with additional low-calcium foodstuffs.
Caution: Use only as directed. If an excessive amount of grit accumulates in the feed troughs, reduce the level added.
Important: Provide free choice next to feed during the laying season, or mix 1 lb. with 20 lbs. of feed.
