I was just browsing to see if anyone else had a hen with a comb like that. I have one whose comb flops over on the back just like yours, shes some sort of black sex-linked hen. I also have a white leghorn who basically is blind in one eye because the comb flops over so much to one side.
no picture of the leghorn, but you get the idea haha. sorry!
