Any chicken can be a meat bird. All comes down to quality, size, and growth to maturity rate. Crèvecœur chicken is an ornamental with moderate egg production. (120). Houdan is a dual purpose with slightly better egg production. (150). I personally would not focus on ether as a meat producer.
Here is the only way I think it would work to some degree. It would not be economical compared to raising broilers, but good in other ways.
By your name, I assume you would be hatching your own chicks. (chicken, or incubator regardless). If you can, then do lets say 50 at a time. 50% will be one gender and the rest the other. At about 5 months, give or take, your cockerels will start to act up. It is that time you start to eat them. The meat is still tender enough that they are not just soup birds. Yes, they are still smaller than broiler chickens, but so what. Just do 2 instead of 1. This way you are utilizing the chickens for their intended purpose. Do you want me to tell you what the hatcheries do to the males at sexing process of day old chicks???

Yes not all,but the few that they keep are used as peanuts in the extras they ship. Pullets is what the majority of chicken owners want to purchase.
So now you are left with 5 month old pullets. These are desired chickens that can be sold for a decent price, as many peeps do like started chicks. In short while, they will start laying. If you keep large flocks, your option of course is to sell the eggs.
If you strictly want to focus on meat birds, then I suggest Cornish X Rocks, or Red Rangers. Your feed to meat conversion ratio is the best with these. Red Rangers mature slower, so many peeps like that option. CornishX are ready to eat at 8 weeks. Yes, if you free-range them and limit their feed, they mature somewhat later. You may be faced with processing a larger number and sending to freezer camp.
WISHING YOU BEST......
