Help! Hen or Roo and why?

[Hotrodblond]

I have 2 and I thought they were pullets but now I'm starting to wonder... I'll post the one I'm really starting to think roo but I'm not sure, what do all you wonderful eggsperts think? "IT" is about 7 weeks old...

Their tails look like boys to me

Cockerel feathering definitely too.
