I appreciate that. My problem is that I don't have a lot of extra freezer space, especially during summer when I'm freezing tomatoes, berries, and other stuff until I have enough to make tomato sauce, jelly, or whatever. I save bones and carcass parts to make broth. I often have to can a batch of broth or sauce before I can butcher more chickens. Just managing freezer space.
With your experience with game birds, you don't know how old they are so you have to be careful how you cook them. The advantage with chickens is that you at least know how old they are so you have more options on how to cook them.
Something you might consider is to get one of those meat bird selections from a hatchery. These are the extra males they get when they hatch, most people want pullets instead of cockerels so they always have a lot of extra cockerels and they sell the chicks relatively cheap. You don't know what breeds you will get but read it carefully to make sure they are dual purpose males. Decide which of them suits you best for breeding. Plus you get to eat all the others.
