They should. They will not come close to matching the true "broilers" in rate of weight gain or feed to meat conversion rate, but they should give you a good dual purpose chicken for meat. I'd suggest not harvesting them until they are at least 15 weeks old so they will be a different texture than the broilers. I think it is age, not breed, that makes that difference. You may need to cook them differently than you would a seven week old broiler.
If you feed them the regular broiler ration, they will grow better than just a regular diet. But the rate of gain per pound of feed will nto be the same as broilers. There is a good chance you will spend more on feed than you save on the basic cost of the chicks. I got red sex link roosters with my last order for this very purpose, but I free range mine. Feed cost is not critical for me.
