I’ve done the raw and fed the necks. They are cheap, you just gave to dial in the percentages of bone to meat. Buy bulk from a local meat market or grocery store. When I fed raw I actually worked at the grocery store and had them order me 40# cases of chicken necks, backs, and feet, feet I think were 20# boxes. I also ordered turkey necks. I feed chicken, beef liver. I feed chicken heart, gizzards. I ordered beef from Pet carnivore and picked up 100# of their beef chunks. I looked all over the internet for freezer burned meat and became friends with a local show rabbit breeder who gave me her culls. I also found a guy that had a rabbit problem with his garden and borrowed him a BB gun he returned me over 20 whole rabbits for the gun and ammo. I got into fishing and caught my dog wild fish and hunted squirrel when I could. If I ever got lucky enough to get a deer which I got 2 deer when I was feeding raw, I kept a majority of the good stuff the dog got the rest.
