Why and What to Do

amy elizabeth | TBN Ranch

About 95% of the egg a hen lays is calcium carbonate by dry weight. Over a year’s time, the calcium she puts into her eggshells could equal 20 times the calcium that’s in her bones. So it only makes sense that a steady supply of calcium will help her stay healthy and produce strong egg shells.

I suggest ground oyster shells, and I recommend putting them in their own container so the hens can take what they need. They like them, they’re readily available in feed stores, and they’re not expensive.

Feed Variances and Calcium

If your hens are fed high quality layer feed and get nothing else, their calcium intake is probably sufficient. But if they’re in the yard, fed table scraps and scratch feeds along with commercial feed, they are good candidates for a calcium supplement.

Note: Only feed oyster shells to hens already laying eggs.

    I went egg-collecting with my little boy. Some of the hens had started oyster shells and some had not because the owner had not started the newer hens on them. We put the eggs in cartons and my little boy happened to drop the ones he was carrying. The eggs of the hens whose diets included oyster shells survived… You can guess what happened to the others!

  2. Most feed stores sell the ground up shells in 25 and 50 pound bags. They definitely help make the shells harder and help in the digestive process within the hen. Good post, many are unaware of this. 🙂
