He looks more white with black bars than the other way around in these pictures so I will vote rooster also. Plus the legs look significant and those tail feathers are way more fancy than my girl of the same age. I think another sign for a female is a dark color on the front of the legs. Don't give up hope until you have proof, though -- I had two he/shes that were SO looking and acting like roosters and they ended up both being girls.
