Can someome please explain? This is a photo of my two 'hens', the one in the back is the one I thought was a roo but all of you said 'hen'. I believe all of you, I do.. but I can't figure out why then they look SO different. They're both the same age, from the same place and both supposedly hens... is it just a variation of breed? Is one of them crossed? Is one just ugly? I don't get it.
