Red Stars are very similar to my Golden Comets. I bought 6 last year. One lays only fairy eggs about 3 times a week. The high production sex linked breeds often have reproduction problems. So if they were old enough, my guess is the Red Star. But 10 weeks old is too young.
Feather pattern is female. Males have solid patches near shoulders. Comb and wattles are advanced which make one lean towards male. If I had to bet, I would say it's female. I have a SLW that was miss identified 4 years ago due to comb but the feathers said female. She is a very beautiful hen.
