Firedove,
I feel your concern. I have some Partridge Wyandotte Bantams that look pretty good -- with that one exception. Last summer my two kids each showed a cockerel and a pullet. The judge just dismissed them out of hand for being "bunny tailed." He was referring to the pullets, but somehow dismissed the cockerels as well. I guess it was guilt by association. I admit that the standard calls for a different shaped tail, but that makes it really easy for judges to just pass them by, even if they are otherwise "perfect" specimines. Having been to a few open shows, I've looked at a few Wyandottes and can tell you that finding one that looks like the picture in the Standard of Perfection is nigh on to impossible. It's a shame though, because the breed has so much to offer, and (in my opinion) so much potential. Keep breeding for correct conformation, and don't give up.
