Gender help please

[Timmee81]

i was wondering if anyone could assist with clues as to genders of my three 3 week old chickens.
I have looked and although they’re only 3-4weeks there’s currently no reddening in wattles or wattle development in Australorps and in the ISA she has slight wattle development but crest and wattle are complete yellow. No change in colour at all. I have attached some pics. They’re not the best though sadly.

Too young to tell. If you see wattle development as young as it is than its definitely a male.

If it don't have spurs, then it's not a roo. But if it does, it has a possibility of being a cock or a hen.

The extra toe-like nail is a spur, fyi.

That one might be a male not 100% sure.

I would repost when they’re 6+ weeks old, too young to tell

Can you take a side pic?

Hmm all of the chicks at the store had spurs. So guess I’ll wait and see
