From what i can see you have pullets.
I may be wrong though. I hope for your sake they are.
These are my pullets and they are only a week or two older than yours!
Thanks Greenthumb83 ! We think they're pretty special
The "girl" we are most concerned with is the white leg banded lady. I wasn't sure about the shape of her saddle feathers - they did seem a bit longer and pointier than the other girls, however nowhere near the look of saddle feathers of a full grown rooster - I can't seem to find any pics of 23 wk old Australorp cockerals to compare to.
I'm in Australia - Canberra. One of the southern cities. Temp ranges from -6C on a few winter nights to a couple of 40C days in summer and we found that the Australorp (Bruno) from a batch of 4 different breed pullets we purchased 8 years ago coped with the temperature ranges well.
I purchased 6 fertilised pure breed eggs from a small property out of town when Bruno went broody (a couple of weeks after her only remaining companion died) - so no, not hatchery eggs as such. All six hatched out but 2 showed their true colours at about 10 weeks (attempted crowing and very developed combs and wattles) so they were returned to the breeder . The remaining 4 (1 out of the pictures) still have not started to lay whereas bruno started to lay at 20 weeks so I was starting to have my doubts.
Bruno was purchased as a six week old from a hatchery and we couldn't fault her. She has hatched out clutches of 6 twice and is such a great mother. She still gives us 3 - 4 eggs each week . Can't wait until I'm collecting more!
I have a handful of Australorp chicks and I wish they would grow up to look like that! Haha i doubt they will though. I have 5 pullets and a cockerel (I'm keeping him for now).
Let us know when you start getting eggs from these girls.
Just another thing that makes me kind of sad about our hatcheries here in the US. I mean, they churn out the birds and make them affordable, but folks start calling any black bird an Australorp. Your ladies are beautiful and show some nice shape, something we don't get in a run of the mill bird here.
And I do think you'll have eggs literally any day. If they're free ranging , you might start going on some egg hunts or confine them.
