Thanks, I'll check it out.A friend of mine told me about this. I was a little skeptical, but it has been pretty accurate so far with both my Ameraucana's, and the Swedish Flowers Hens. It is always easier for me if I can visualize it so rather than me trying to explain it take a look at this article @ animalsciences.missouri.edu/reprod/ReproTech/Feathersex/index.htm.
This link doesn't seem to be working but if you google "feather sexing in chickens" it comes up as a article from Jan.5, 1999. Hope this works for you.
