I purchase whole lamb and have 3 packages of their organ meats. We don't consume it fast enough so I am considering giving it to the chickens, as from what I've read, some meat would be fine. It is completely grass-fed lamb organs and I can't bear to waste it. How should I prepare it? I don't have a grinder yet, but I can cut into chicnks. Should I lightly cook it, leaving it a little raw inside? Or cook it all the way through? Any organs I shouldn't give them? I have the heart, liver, spleen (?) and kidneys. I'm assuming Winter is the best time to give this to them since bugs are almost non-existant. Thanks!
