Also, yes oyster shells. Also just learned they love love shrimp shells if you eat shrimp. Dry the shells some first. Great for calcium.

Shrimp shells are fine to feed to chickens, but are not a good source of calcium. They are mostly made of protein (just like feathers, fingernails, and hair are mostly made of protein.)

Hummm, my vet told me yes, calcium. Protein for sure. My eggs get thicker and yummier...we eat a lot of shrimp.
