Frequently Asked Questions

Maybe not, but it's cheap insurance. A quality layer feed usually provides enough calcium, but hens that forage a lot, get plenty of treats, or are high-production layers can run low even with good feed. Offering oyster shell free-choice means they'll only take what they actually need.
Roosters usually don't eat much when it's offered free-choice, so small amounts aren't a concern. That said, too much calcium over time can cause kidney trouble for roosters, which is why keeping it in a separate dish rather than mixing it into feed is the right approach. Your hens will self-regulate, and roosters typically leave it alone once they've had a taste.
No. Hens instinctively self-regulate their calcium intake and will take what they need. That's the whole point of offering it free-choice in a separate dish rather than mixing it into feed. A hen won't overeat oyster shell the way she might overeat a treat.
