I toss stripped deer carcasses to my chickens every November and you'd think they were piranha, not chickens. They pick the bones clean of every scrap of meat. Lots of protein, raw and unprocessed. Wild birds scavenge too, and the fat and protein is good for them as a portion of their diet.
Hubby is out deer hunting today, and I'll hunt this evening and this weekend. So I'll keep that in mind! Thanks!
