I am in the same position. I'm trying to sell some but would rather butcher them. We have butchered an old roosters on our own but it takes time we don't have right now. We have no butcher shop that will butcher chickens anywhere nearby. I am checking with ethnic groceries nearby to see if I can find a someone. The old roosters was a lot of dark meat (typical of free range - I'm told). We made stock and feed the dog for a few days.
I just sold a Danish Leghorn cockerel for $20. At four months, he cost me $11 in variable cost (chick cost, feed). Probably a lot more in fixed cost (coup, watering setup, feeders).
Hi, welcome to BYC!
Ethnic grocers is a great idea!
Butchering old roosters takes a lot more time than younger ones we discovered. It took a while to wrap our head around the whole process so our first boys were a bit older and our inexperience took 2 hours to butcher and SKIN a single boy (we haven't plucked any yet). Fast forward several months and my daughter was worried about it being harder to do young boys from not being able to get her hand inside the smaller body cavity. To our surprise, there was much less connective tissue and the bones were more flexible so the process dropped to a half hour per bird instead of 2 hours, with not much more experience.
The amount of dark meat won't be only relative to free range, but different breeds have different characteristics. Some are double breasted, while others are not. What I think is typical of free range is longer legs. Oh, and I bet your chickens would have appreciated some of that extra meat!

We eat the older ones as well.. but use like shredded chicken in burritos or enchiladas, after making stock.
I can't count my fixed cost... those are what make my eggs cost me probably $10/dozen!

Keeping chickens to enjoy the eggs/meat certainly isn't cheaper than just buying them. But the pay off is huge and I don't spend $ on going to the gym or a therapist.

And don't eat nasty blood river meat from "big chicken".

Since we process only a couple at a time, we get to air chill them in the fridge.
