HELP! I don't know the gender of my Seramas, can any one clue me in??

Chick One:




Chick Two:




Chick Three:




Chick Four:



The rest of the Serama chicks, probably too young to tell the difference.



The top 3 have been fighting non stop even though they all have been raised together making me think their aggressive nature could mean they are cocks. The bottom 4th is a sweetie, I think she is a hen. Any clues? I need to have an idea so i can find a home for the Roo's, as the city doesn't allow them. Eeeek!

Thanks!

I should add the top 3 are around 4-6 weeks old. Not sure about #4, I would guess 4 weeks. The others are under a month for sure.
