I found the thread very interesting. I have never owned any silkies..yet anyways.
I have however owned different breeds of chickens and for them I would disagree with the statement
the dance only a ROOSTER will do.
Now if it is true only for Silkies, I don't know, but for other breeds it is not always true. Kind of like a hen crowing or growing spurs. Most the time "the dance" is only predominantly in males, but some females (mostly the more dominate like the head hen) will do this dance. Most occurrences that I have seen have been in gamey and flighty breeds, but have seen a few cases in other breeds as well. 
Do you mind stating those breeds? I have a really bossy head hen and have never seen her do the wing cutting. I will note in the thread that some game breeds can do this, but have never heard, nor seen it happen. 
ETA: Adjusted it to state that some hens may engage in this behaviour, just as some may crow. It usually happens if the head hen is taking over the rooster duties.
Thanks for pointing that out! It really helped

But I agree, they are definitely harder to sex at a young age than almost every other chicken!
