Newbie, is one of my hens a Rooster? Video attached

[MotoChicken]

Hi I am new and a few people have told me one of my hens is a Roo/Rooster the light one in the video > http://www.youtube.com/watch?v=wbNJmP_p3jo

Is there a way for me to be 100% sure?

Thanks for the help Jerry

just have to say love your coop!!! from what i've read on here about barred rocks..your light colored one is a roo...i have 2 barred rocks that are 14 weeks old and mine aren't as light and their combs are just now starting to turn pinkish...sorry but i'm new to the barred rock community so maybe i'm wrong. good luck!!

the lighter of the 2 chicks definitely looks like a roo to me. can you get a couple good pics of both of them? a full body side shot and a head shot. that would really help with trying to sex them.

PS: i like your coop and the cables to open and close the door etc. is a great idea
