I'm starting them off at $5.00 each. If I have them longer then 2 weeks then the price will go up slightly each week. I should know genders on mine fairly accurately by 5 weeks old. Mine the key thing to look for to tell if its a rooster early on is wattle development. The breeder of my original Marans told me that if wattles started growing before 4 weeks it was a boy. So far with the ones I got from him, and the chicks i've hatched its been true. But then your line may develop at a different rate then mine do.
