This is too juicy to resist. Take a visit to the good atheist and learn about the miraculous chicken that transformed its gender. My comment at the site pretty much sums up my views on the deal, but I thought I'd share my personal miraculous gender transformation story. (Sounds like the beginning of a bar tale, doesn't it?)
I fell in love with a kitten I named Ace because it had a black marking that looked like a spade from a card deck. Ace was lovey, cute, friendly, and the most despised creature in my home by the other cats. I gave "her" to a co-worker because my male cats kept going berserk whenever she was near.
The co-worker renamed "her" Belle, which I thought was a stupid name for this rugged little kitty, but whatever. If it made her happy...
Belle turned out to be the cat's drag name because within six months "her" very large testicles appeared and she sprayed all over the co-worker's house.
The vet said, "Oops, sorry. It's hard to tell sometimes."
The co-worker said, "%&*() ^#%^@ *(@7**!$^, Belle, ^#&!*"
My cats said, "Told you she was a faker. That guy was messing with our turf."
Moral of the story - sex traits come in all kinds of mysterious varieties. And isn't that what we like about nature?
