A simple, effective calcium supplement for your laying hens — and once you see the difference in eggshell quality, you'll want it in the coop permanently. Processed locally by Heim Feed Mill right here in Minnesota, this free-choice calcium blend delivers what laying hens need most: strong eggshells and healthy bones. Because it's a calcium supplement blend — not just oyster shell — it provides a broader calcium profile that hens can readily absorb and use.
