I think i have chicks that are half Cornish X But I thought that wasn't possible because they're too heavy to breed naturally. My laying hen recently hatched out 4 chicks. They've feathered out white, are growing freakishly fast, and have that walking like they have "corners" gait. I can also tell which ones are male and female already, which I've never been able to do with other chicks that the hen has hatched out. I had a batch of free range Cornish X males, and the timing works out for one of them to be the dad. They were constantly running around after the laying hens. Could the chicks be half Cornish X?
