Pullet or a Roo?

[AlynaD]

5 week old Turken I have 3 others and this one's comb is bigger than everyone elses tho not enormous will I need to wait a bit longer to see if I have a pullet or a Roo?
also when do Roos begin to crow?

I'm thinking pullet but I'm not experienced with Turkens. My roosters started to crow at 4 months. I think it depends on the breed, though.

I'd like her to be a pullet, she is adorable. But please post new photos at 8 weeks or so. It would help if you knew what type of comb her parents had.
