I got 2 Silver and 2 Golden Sebrights straight run about 7 weeks ago, and 1 of the Goldens is definitely a rooster. Tragically, I'm not allowed to keep roos in my hometown, and I'm pretty heartbroken as the rooster is the most friendly, cuddly, and outgoing of the 4 chicks! I think I still have a bit of time before he starts to crow, but I wanted to start looking for a loving home for him now. Let me know if you're looking for a delightful little bantam!
