This has probably been posted before, but I'm not coming up with anything definitive. I just trimmed all fat and sinew off a big leg of lamb, and kept a baggie filled with all the trimmings. I figured I could feed my birds a little over time - particularly over the winter, when they might like the fat. My question is, do I give it to them raw, or cook it somehow? And if cooked, what's the best way? Any help would be appreciated!
