8-9 Week Lavender Orpington- hen or roo??

[FlockinAround]

This is our first time having chickens and we are really hoping they are all gals because we aren't allowed to keep roos...our other 2 are a black australorp and blue sexlink so we don't have other orpingtons to look at side by side...this chick's tail is SO much bigger/longer than the other two chicks (but maybe that's a breed specific thing??)
Age aprox 8-9 weeks: What do you think??
