You're welcome. And thanks for the update. It just demonstrates once again how difficult young Silkies can be to sex.
Silkie Pullet or Cockerel? - Page 2
It really is. Even now, he still acts like a hen. He crowed once in his life (only when one of my pullets went broody and he couldn't find her), but once he did, he's never crowed since. I've never ever seen him mate with a hen, although the eggs were fertile so he was, but it must have been very rare since I spend most of my free time with them and have never seen it. He does have bigger spurs than the pullets though.
