HI Leigti , WOW i never knew that but we have always fed our dogs raw meat just not the bones so yeah live & learn, but still i would grind up any meat with bones just to make me feel better HA , we never kill any thing & about old hens we would just keep them all, since...
my sister in law back in the late 60s gave me some of her butchered old hens for dog food & i gotta tell ya its not an easy task , its lots of work keeping all those bones from killing your dog
