Question about the sex of my 10 week ameraucana

[Farmercharmer]

For a long time I thought our ameraucana was an Abe, the comb was pink from week 3, likes to chest bump, seemed semi aggressive.

The thing is his comb has not grown in several weeks which has led me to question that maybe Abe is a liberty bell. Thoughts?

Hmm, the feathering looks like a pullet but some EE's are late bloomers. Just judging by the bright red 3 row pea comb I have to go with cockerel. Someone will correct me if I'm wrong. Either way that's one beautiful bird!
