Does yellow tips on a black Austalorp indicate something?

How old is this bird??? I'm sorry, but I keep seeing cockerel characteristics when I look at it. Then again, I'm not very familiar with exactly how the frizzle gene interacts with the male sickles and hackles.

 

Oh yeah. DEFINITELY a cockerel!

And from the looks of it is not a complete Australorp. The comb doesn't seem to be a single comb.

I can't tell if there is any feathering on his feet (even the slightest) but I will say he looks an AWFUL lot like the Light Brahma (cock) X Black Australorp (Hen) cross we did for meat and eggs.

 

Oh yeah, that's a boy. Look at the droopy sickle shaped feathers by the rump. Not a pullet.

 

I just bought one , she is 2 weeks now and so adorable. I was wondering how are they at egg laying? The chicken farm I got her from said they lay as much as my RR and that they would get along great with my RR.

 

Well, the world record for laying eggs is supposedly held by an Australorp...
