Buying Guide: Oyster Shells For Poultry And Crafts
- What to choose for laying hens: Look for pure oyster shell calcium supplements labeled for poultry. Crushed or pullet-sized forms can aid easy consumption and absorption.
- Natural vs. processed: Natural oyster shells without additives are generally preferred for minimal processing and reduced risk of contaminants.
- Size and ease of feeding: Smaller, crushed shells are easier for younger birds; larger shells may require experimentation with intake and feed mixing.
