Just my experience. I've raised about 50 chicks and I haven't had a pullet yet that has had a red comb and wattles at 8 weeks. I'll keep my fingers crossed that it turns out to be a girl!
#3 looks to be the only hen. Sorry. Good looking birds though. List them on Craigslist to sell or trade. Make sure you list what kind of chicken they are and the age. It helps those looking for certain birds. Also, big flea markets are good and in some areas there are chicken swaps. Good luck.
