I recently adopted a chicken from my dad's coworker. He stated that she was a leghorn, so it came as a huge surprise when she came home and looked around 10 pounds, if not bigger. First thought; that is not a leghorn. I have no experience with white rocks or broilers. Her legs are massive, so are her breasts and body overall, but she does not look like her body is giving out at all, which surprises me if she's actually a broiler. According to the previous owner, he got her as a chick back in January, her hatch mate died young, which also makes me think broiler. But this girl is 8 months and has no problems other than her massive size. Could she be a white rock? Or is she most likely a lucky broiler? How much should I feed her so she doesn't start developing problems and stress on her body from the weight if she's a cornish x? Thanks!
