I hope you saved the heard, liver, kidney and bones. You can make great rillets with those organs from game hens. Pheasant bones, if roasted, and then simmered in water for 24 hours, then finished with an hour or two of garlic, leeks, sage, celery, carrots, parsley and onion is deadly. add a bit of vinaigre or acid at the start and it leaches some extra calcium out of the bones.
