Well to be fair, if you were served some nameless meat, would you be confident in your ability to identify human and/ or not like the taste of it?

Chickens will eat egg shells, and it's apparently a good source of minerals for them. You do have to scrunch them up, or else, from what I understand, they start associating egg shells with food, and start pecking their own eggs.

Its also good to bake them for a bit. It helps with the 'scrunching' and nutrient availability (so I've been told).
