Sexing mixed breed chicks

[Farm life101]

Hello fellow chicken lovers!
I just had 4/4 babies successfully Hatch and I’m thinking they are all girls so far. One still isn’t fully fluffed so I’m waiting to check that one but just wanted to make sure I got a second eye to look at these babies. There are two polish crosses and then 2 full Ameraucana but I’m not sure who is who as I basically have 2 sets of twins lol. I included pictures of the chicks and their wing feathers.

thanks!

I still don’t understand which breeds or breed mixes can be wing-sexed but if yours can be, then I'm pretty sure they’re pullets.

Most chickens cannot be feather sexed. If they could then there would be no need for all those vent sexers the hatcheries employ.
