6 week old Australorp’s. Guesses on sex

[Bcolpetzer]

i have these two Australorp’s got at same time. Guessing about 6 weeks or slightly older. Got them 5 weeks ago and they was a 25 cent clearance chicks at tractor supply. I am starting to see a difference in them. And am guessing may have one of each. What your thoughts

Hi!

It looks like the chick in front is a cockerel. The comb is very big and red which is a sign of it being a cockerel. They are both very pretty!
Hope this helps!
