8 week old australorp hens or roos?

I'm going with all 4 are cockerels, with the possibility that the first one *could* be a pullet.
I've noticed that when you have more than one cockerel, the dominant one will develop fastest and the bottom of the pile of males will develop slowest.

I'd repost at about 13-14 weeks and you'll know for sure due to gender specific saddle feathers.
