Most animals we eat today cannot truly be called "Paleo" as most are domesticated versions of the real animals our ancestors would have eaten. Still, compensation has to be made, this has to be practical. Free range chicken is what's available.
Free range chicken, slow roast in the oven overnight, in oranges, dates onion and carrot.
Served with pineapple and bacon.
I'll make a soup with the remains and the juice.
