Higgins Sunburst Mineral Grit (Bird Supplement, 6 oz) – A mineral-rich digestible grit made from 100% crushed oyster shell (not gravel) to aid the digestion of small birds like canaries, finches, and parakeets. It’s naturally high in calcium and fortified with essential trace minerals, supporting strong eggshell formation and bone health. This grit is colored by its natural oyster shell content (no artificial dyes) and helps birds grind seeds in the crop for better nutrient absorption while keeping their beaks and digestive tract healthy.
