I bought ten cornishx's last Sunday. In a weeks time they have doubled in weight. Yeah! However, I notced last night that they are growing lopsided. All of them seem to be growing a bump on the right side of their breast. I have never had cornishx before so is this "normal"? Is this how they grow and is it kinda weird because they grow so fast? Please see my pics and I hope you can see what I'm talking about.
