i have 2 silver-laced wyandottes. for the longest time i couldn't tell them apart, i just called them the twins. until a few weeks ago (not sure why it took me so long haha) i noticed that they have different combs!! i looked it up, and sure enough i read that wyandottes normally have a rose comb. my one girl has a rose comb, but the other girl has a single comb! the hens are identical otherwise, and i got them from the same farm last summer when they were already a few months old. i don't think they were hatched at that farm, but i think they come from the same place. so is this just a fluke, the one hen maybe coming from a different mom or something?
