So one of the chicks I got a few weeks ago is a BSL chick, mostly black except for some tan on her chest and under her neck- her head was solid black, no white spot whatsoever. She's almost 5 weeks old now, and I've noticed her comb is getting red and some of the new chest feathers are barred. She's also feathering in slower than the others and the tail is more sparse. Could she be a he? How could a BSL be a male with a solid black head? Or can females have some barres feathers? Here's a pic from today:
