All of the chickens I have act as though they’ve never been fed, but I don’t think these white ones are eating more. When I first got all of them these guys were bigger than the rest, but at this point everyone has evened out in size.
They probably aren’t Cornish x then, as they are like vacuums with food. I think they might be white rocks, but again I’m not sure.
Maybe slow-growing Cornish X?
I would hold off. You probably won’t know what breed they are for sure until they start showing signs of either being a broiler or being a layer or dual purpose breed. If they start going downhill I would cull them, but only ones that are going downhill. They might be separate breeds but I don’t know.
They are a broiler breed, though not Cornish X. What would your plans be for broilers? Would you process them? The pullets could very well reach laying age, but not be great layers. Obviously the cockerels won't give you any eggs.
My Cornish X was my best layer. She layed an egg a day for 2 years and they were the biggest eggs I had seen.
Cornish X are a hard bird to keep alive till maturity, so props to you! How did you even do it?
Are you sure it wasn't a white Rock? They are excellent layers. Cornish X are not, and most do not make it to 1 year of age.
