10 week old austrolarp roo or pullet?

[chrissynemetz]

I agree, your Australorp appears to be a pullet, but the cuckoo Marans looks like a cockerel.

Yea.... that's a French cuckoo marans, cockerel... If its the same age as the aussie.

It is the same age

I’ve had male and female BA. Your BA is a female as noted by others. If male, it would already have a more prominent comb at 10 weeks.

My BAs have all been good in the flock.
