Yes. Orcs even eat their own kind.
(A generalization; individual orcs don't want to eat family, friends, or individuals they admire (e.g. a dwarf comrade or even honoured foe…).
And no orc will eat sentient foes when beast-meat they like better is to be had.#Realmslore— Ed Greenwood (@TheEdVerse) July 17, 2021
Dare I ask….is it the same with Ogres? On the devouring end, not the devoured.Pretty much, in the wild, but ogres have a far more developed cuisine in some places: herbed and spiced mixed-meat dishes, fowl-meat inside rolls of herbivore meat, gravies, lots of curing.#Realmslore
