* Oh, I was under the impression that those Cornish X birds could not be grown to full size, so I thought you were talking about something else that I didn't know about. My confusion.* Are you pulling my leg?
White Rocks are white Plymouth Rocks, but those sold by the hatcheries fall short of looking like true, pure bred, Plymouth Rocks. True Plymouth White Rocks are larger and more meaty than the hatchery version.
Must be hard to grow them though. The ones we had could barely walk by butcher day.
So, if you cross them with your other birds, are the offspring more hardy, less prone to heart and other problems? Do you use the pullets or use a cockerel? I would think a cockerel wouldn't be strong enough to cover many hens.
There is a hatchery that sells white birds. They only sell a few breeds. I was thinking of trying some for meat, but maybe keep one for breeding.
What do you think?
