Definitely not a Dominique. Doms have rose combs, that's a single comb. It's not a Barred Rock either, the barring pattern is not correct. My guess is that he is some kind of a mix. Looks like he could be good as a sire for a meat bird.
If you try to hatch enough boys to eat much meat you will soon be overrun with girls. I don't need that many eggs, can't afford to feed them or build enough facilities to house them. Do the math. I eat the pullets I don't need for replacements but many people sell them, maybe as POL (Point of Lay). Many say they can get enough money selling them to pay for the feed. Selling them does not meet my goals, set-up, or the way I want to manage them but is a viable option.
