Oyster Shell is a premium source of calcium for building stronger egg shells.
Provide oyster shell in a separate dish once your birds start laying eggs. Always offer fresh, clean water.
Your girls will start laying around 18-20 weeks of age, so if you plan to supplement their calcium source, have a bag of Mile Four Oyster Shell ready to go around this time.
Mile Four Oyster Shell is a mixture of coral calcium and crushed oyster shell.
