It is very odd that it would have coloring so close to the pullets' coloring. But man, that breast is at least 4 times larger than the other pullets that are the same age. So something weird is going on there.I think some of the hatcheries may have made some "Ooops" cockerels that are colored like pullets trying to get the male sex-links to be meatier since they sell them for meat birds. I was looking at the descriptions on some of the hatchery websites for their sex-links and it reads like they are using at least one hybrid to make them. I really wish I could find it, but I saw an e-mail somewhere that TSC sent back to a customer where they did admit to selling some this year.
