I'm not sure you'll be able to tell much because the pics aren't the greatest. It's still chilly here, so we didn't want to take the chick out of it's enviroment to get the pics. I couldn't get a good view of the comb, but it's comb does not have a row of tiny little bumps on it the way my brahmas do. The first pic is the cochin? with my darkest brahma (standing in the pic) for comparison. Hooligan, see ya later today!
P.S. My SO agrees that your JG is just a tad bit fiesty!
