Baking eggs shells to feed chickens

[Teresa D]

Hello, Seeking information on baking the chicken eggs and using them for calcium for my chickens when they start laying eggs. I know this is the best site to find any and all of my information. Thank you.

I do it. I bake them 350 for at least 5 min, cool, crush to bite size pieces.
