Hi! I supposedly have two clean-legged BCM pullets (8 weeks old). Problem is, I've also got two 8 week old Black Australorp pullets and I'll be darned if I can tell them apart! (Keep in mind, it's my first time raising either breed). They looked pretty much identical as chicks, too -- the ones that I think are BAs seemed to have a little more white on their faces. Is there any distinctive way to tell the two breeds apart as adolescents, if you're not overly familiar with body type?
