Roo or pullet Easter Eggers?

[Lilac Farms]

I bought 3 Easter Eggers and what I was told were two barred rocks. The barred rock is definitely that, but the other has none of those markings and is all black. I’m starting to think she’s an Egger. Also worrying she may be a he, along with another egger. I’m adding some pics. I know this is a repeatedly seen thread, but it’s the first time I’ve had a doubt about one or more of my chickens.
The all black is the one I think might be a roo.
the mainly black and white one is suspect too.
please let me know what y’all think.
I appreciate it.
Josh

Thanks all. So the all black EE and the Black and white EE appear to be cockerel and the white breasted EE looks pullet?

The black ones are both roosters. The white one is a girl... Not sure about the other one, might be a roo
