This last weekend I purchased two chickens from a natural raised farm I buy a lot of my meat from. I just took them out to a lake in the woods and my wife and I just cut off their heads, bled them into a mason jar, then skinned them, gutted and had some of the freshest tastiest liver and heart we have ever eaten (even if it is tiny haha).
I would recomend doing something like this.. I didnt find it half as traumatising as I thought it was going to be, and it might have taken 20mins to do both..
We took the carcass home and just cut the meat off the body as we wanted it (and omg it was the best chicken we ever had, diced up the breast and mixed it in with an egg yolk and a little spice).
When we were done we threw the feet and bones into a broth and made one tasty broth.
