Turns out that "she" is a male, since my hen's eggs are fertilized, but he's never crowed and I've never seen him mating with her, which is weird. Anyways, I'm glad he doesn't crow since if he did I wouldn't be able to keep him.
Thanks for the help everyone!
You're welcome. And thanks for the update. It just demonstrates once again how difficult young Silkies can be to sex.
