They must be nearly 15 weeks old now, im very confused as many have dark combs and wattles! iv selected a few who i am struggling to sex the most. I also bought them as silkie cross? but what are they crossed with? Chick 1 Chick 1 again and chick 2 Chick 3 Chick 4- mainly confused on what breed it is? could it be a copper blue maran? Any suggestions welcome!
