Emily & Chicken Boy,
I can assure you that these are not any sort of hoax F1 hybrids. I'm 3 generations in to breeding them and they are quite stable in their characteristics in a manner that would not be indicative of a recent hybrid.
The only variables I 've really seen are in the leg color, with some whites showing up.
The only real debate at this point is whether Roy Stacey "rediscovered" them or created them years ago. If Mr. Stacey developed the breed rather than simply bringing them to the attention of the poultry world, well, he did a fine job. They are great birds.
But, to me it's irrelevant. Kentucky specks are gentically stable, have great personalities, are good layers and they provide me with a great deal of pleasure in keeping them. I'd love to be able to show them as an ABA-accepted breed at our local shows and at national shows in Stockton and Columbus; but if that never happens, I will continue to breed them, promote them, and sell fertile eggs to those who are interested in them.
