How to sex an Australorp age 3 months

[cjpines]

We have a 3 month old Australorp we just bought from a breeder. He said the bird is 80% female, but not for sure.

At what age do you tell the sex. We hope she/he is a she. I know the comb will tell, but not sure when that happens. She has no comb yet.

Please advise,

By 3 months, you should be seeing comb and wattles if it's male. Try posting pics over in the What Breed or Gender thread.
