I have four 16-month old Buckeyes from unknown hatchery stock. They are dears in personality, smarts and friendliness. Mine vary greatly in their physical build and in their laying frequency. I agree with
@goodb from what I've read too the lines have been tinkered with for both greater meat and more eggs, which I'm not crazy about as it affects their longevity. I think I would prefer in future ones that have been kept more to their heritage qualities. Unfortunately that is not the trend in breeding these days.
