If you eat eggs, make sure you make the best use of those shells! Most of an eggshell is calcium. In fact, about 95% of shells are calcium carbonate…the same stuff that sea shells, coral, and limestone are made from (the other 5% includes proteins, calcium phosphate, and magnesium carbonate). Here’s a list of what you can do with those shells so the calcium and its brittle shell don’t go to waste.
USE EGGSHELLS FOR THIS
1) Give your hens a calcium boost. Eggshells contain 95% calcium, and hens need calcium to lay eggs that have those strong shells. There is nothing unhealthy about feeding your hens eggshells, as long as those shells have been sterilized to kill bacteria (see below on how to do this) and offered in ground form. Pay special attention to shell sterilization if you get some of your eggs from another source where you can’t be sure of the laying hen’s health.
2) Give your pets a calcium boost: In the case of eggshells, what is good for chickens is good for your pet. Adding pulverized eggshells to their food provides extra calcium for bone health. And just like using shells for chickens, be sure to sterilize the shells first.
3) Give yourself a calcium boost: Consuming calcium from eggshells can help you, too. In a 2003 study published in the International Journal of Clinical Pharmacology Research, eggshell consumption helped stop bone loss in postmenopausal women. While you can consume pulverized eggshells for added calcium, remember that calcium amounts very greatly in shells, so there is no way to tell exactly how much calcium you are getting (but we know you are getting more than if you didn’t consume the shells at all). Be sure you bake the shells before consuming to prevent ingesting any bacteria if you haven’t washed the shell before eating the egg (see below).
