Dark greenish spot on my pullets leg?

[Liv_loves_chickens]

Hey everyone! I am a 4-H member about to take my pen of pullets (amber links) to the fair. While I was washing my chickens I noticed one of them has a dark greenish spot on its leg. Is this a bruise or what is it? All help is appreciated, thanks!

I also want to know if anyone out there has experience with 4-H and chicken showmanship/judging, and can tell me if I will get marked down for this!

It's just bruise, not sure if it's a deduction.
