Australorp chicks. Age and Gender?

[Matthew__]

We picked up some Australorp chicks and we are not sure of the age and gender. Any help would be great.

This young you can usually get pretty close by looking at their wings and whether or not they have body feathers coming in.

At 3-4 days old chicks get tiny wing tips and start to flap a bit.
About 1 to 1 1/2 weeks old their wing will be half feathered
About 2 to 2 1/2 weeks wings are nearly fully feathered to completely feathered
About 2 1/2 to 3 weeks they start sprouting body feathers and look really ragged
About 4-5 weeks old they're mostly feathered with a few patches of down left
6 weeks fully feathered

Others might have a better timeline, but this is what I've seen with multiple chicks of varying breeds and crosses.

Judging by the pictures I'd guess 2 1/2 to 3 weeks old. #2 looks like it could be male, but I can't tell if the pink patch under the beak is part of the beak or wattles coming in

Thank you for all that information. Appreciate it. I am hoping they are all female, anyway, time will tell.
