Please, help me not to do the same mistake again!

Hi dearest (never disappointing) chicken experts! I want to buy a pullet or grown Aracuana hen.
Got this video from someone. What do you think? Male or female? My first impression is that the black one is a male and the brown a female. She’s been really badly treated by the others in the flock (thereof the featherless back). But more importantly, I don’t want to get another male, fall in love and then wake up one morning from the clear evidence it’s a male and not a female...

thanks a lot in advance!!!
Sara

I think both are girls, but the photo isn't very clear.
The brown one is for sure.

How old is bird?
Clearer pics would most certainly help.
