I only have Coturnix Quail right now but will be getting King Quail. I think they are even a little smaller than button quail. I have pigeons, rabbits, chickens and of course the Coturnix and everyone wastes a little bit of feed, especially the pigeons. So I plan to use them as "Hoovers" in my aviary and colonies. I plan to use the eggs and extra birds to feed my cats and dogs. I think it might be worth it to butcher a large batch and make a bird stew or even a really good bone stock. I have made deviled eggs with Coturnix eggs and it was fun but can't imagine peeling anything smaller. My cats and dogs can eat quail eggs whole, shell and all.
