Calcium deficiency is one of the most common nutritional problems in pet birds. Specially ground for caged birds, Hagen Crushed Oyster Shell is an excellent source of high amounts of calcium and other necessary trace minerals required by all caged birds year round.

Oyster Shell is recommended as a dietary addition during mating season to obtain strong, hard eggshells.

Directions: Mix with bird seed mixture at the daily fresh feeding. Alternately, sprinkle small quantity on bottom of cage three times weekly.
