Can you guys post pics of your Australorps at 7 weeks? I'd like pics of a 7 week old roos and 7 week old pullets. Thanks!
I personally can't usually tell until at least 8 weeks.
Here's one I suspect to be a cockerel at 7-8 weeks. I don't think I have any pullets from that hatch.
Here's a cockerel at 12 weeks.
Here's a pullet at 12 weeks.
As you can see, it'll get fairly obvious in the next few weeks.
