No Need to Supplement: It’s All in the Bag

Calcium is the number one nutrient for laying hens. For years, there has been only one way to provide this key nutrient: by supplementing layer feed with oyster shells.

Now, Purina® Layena®, Layena® Plus Omega-3 and Organic layer feeds include Oyster Strong™ System, an exclusive blend of oyster shell and key vitamins and minerals, like vitamin D and manganese, ensuring a supply of calcium will be available at night when your hens are forming eggs.

Our exclusive Oyster Strong™ System eliminates the need to supplement as all the necessary calcium is included in every bite of our complete layer feed.

“When I switched to Purina® Layena® with Oyster Strong™ System feed, I immediately noticed a difference. Not only does the food last longer, the egg shells are strong and my hens are happy. I wouldn’t use any other feed for my hens.”

“We were giving our hens oyster shells, but still getting soft shells. I switched to Purina® Layena® pellets and by the second day, voila! It was like someone turned on the hardening switch. My eggs now crack in a perfect ring around the egg.”

“I have fed Purina® Layena® for the past four years. A few years ago, I was excited about the added omega. Now, I’m thrilled with the added Oyster Strong™ System. My birds are so happy and the eggs taste great!”
