Help deciding australorp genders

[Sam0strange0]

I am guessing the larger more yellow chested ones are the males and the smaller darker ones are the females? I need a second opinion from someone who knows this breed better than I do. They were hatched on the 28th of July. This is my first time owning them not sure about the wing sexing they all look different to me. I have a feeling the larger yellow chested one is a boy i appreciate any help or tips thank you.

I don't think Australorps are sexable at hatch. You'll have to wait until at least 4 weeks, more typically 6 weeks, to be able to tell. Males will get large red combs and start developing wattles. They're very cute though.

Wing sexing is not accurate unless specifically bred for. Around 4-6 weeks old you will be able to tell based of comb and wattle development.
