Someone gave me a setting hen (eggs and all). She is long legged, very black (iridescent green in the sun), and has black legs/feet. She also had a sort of bald spot or bulge on her chest (?). Is there something wrong with her or is that the characteristic of a particular breed? I have a hunch she is from fighting stock(a lot of that around here), but really have no clue about her breed. Does anyone have any info for me?
