Pullets or cockerels? Please help

This one.It may just be the photo, but its comb looks a bit red to me. I am confident that the Wyandottes are pullets.

That's the same one. I think the red lamp is reflecting in this picture. But I'm low key suspicious of them all at this point, so I'm not ruling anyone out

I agree 100%
1 cockerel, rest pullets at this age in my opinion

This is the same one. I had the heat lamp on for some of these pictures and it made the combs look redder..
