Sexing Welsumer chicks

It is supposed to be, this is what Backyardchickens says:

"Sexing Welsummer chicks: pullets (hens) will have a very defined V shape on their heads and eyeliner. Cockerels (roosters) have a smudged looking V and no eyeliner."

But as Joyfull will tell you, I hatched some Welsummers for her and we were both convinced they were both girls, but they both turned out to be boys!

But then I hatched 3 welly eggs given to me by Animalmad, and I said from early I had a boy and 2 girls, and that's what they were!

Oooo, bossy boots, now That Is Interesting, I've never come across that way of sexing chicks. Do you apply this rule to all chicks or only Welsummers?

Thanks very much ALL I don't suppose you have any pictures as the eggs have not hatched yet so it's hard to visualise, (I'm not counting my chickens yet lol) cheers Mike.
