It looks like my response never posted!
I purchased my AC hatching eggs from Sugar Feather Farm in Vermont and had a great resulting hatch. They're currently growing out on pasture in chicken tractors for the summer and don't eat a ton of feed, so i'm not too worried about costs to raise them. I already have a tentative list of people interested in paying for my cull pullets to have as fancy additions to their backyard flocks, and I'll be culling the excess cockerels this fall for my own family to have as food.
In terms of making the investment worth it, there is an extremely high demand for sexed pullets in my area, but not a ton of breeders selling anything but straight run day old chicks. My hope is to raise all of the chicks I hatch from my own breeding stock to a sexable age. At that time I'll sell the pullets, and retain the cockerels until they're the appropriate weight for processing. This is why i'll be looking to improve the meat side of the dual purpose breeds i'm raising to bring more value and purpose to the necessary existance of these roosters. I followed a similar schedule with the other breeds i'm raising this past spring while I was building my breeding flocks, and I quickly ran out of pullets to sell! The first round of boys are long gone as well, and had a decent bit of meat to them!
With all that being said, if in a year or two I don't think they're worth it to me, I'll demote the ACs to pets, and fill their breeding coop with a different dual purpose breed. One obstacle I'm already facing is finding an appropriate butcher for next season that will commercially process for me. If I can't get that sorted I'll need to operate under my state's exemption and sell whole chicken to individuals. If that was the case, I would most likely have to discontinue working with AC, in favor of a larger dual purpose breed to make it worth my while.
