I'm leaning more towards cockerel on this one. At that age and older, most of my EE cockerels weren't terribly developed/pink, either. Time will tell for sure!
I'm on the fence. I think you'd better wait another couple weeks and post pictures again. My gut says cockerel, but I wouldn't swear to it as of now. I'd really like to see how she/he looks in 2 weeks or so.
