What sex is my naked neck?

[tangled_yarn]

This is Karen! She's a silkie naked neck, about 14 weeks old. I've been pretty sure she was a hen, but she likes to hang out with the roos a lot, and I want to be sure, since I have NO idea what a roo of this breed would look like. Either way, "she" is fabulous and I'm keeping her, I already decided to make a bachelor pad for the boys since we have at least five roos from this batch and I like them and want to keep them all. ETA: the run they're in is not permanent, we're building a predator-proof run. They do have a smaller, completely secure run and coop they get locked in to at night.

Sorry for the huge picture, I can't figure out how to make it smaller!

Thank you! I thought so, but wanted to make sure since I'll have to separate the boys into their bachelor pad soon.
