I also have yet to identify all of them lol. I know my two Americaunas, and the Wyandotte, and the barred hollands and barred rocks, but I cannot tell which is my red sex link and which is my golden sex link. We have one that looks identical to the red sex link pictures ("Lucy") but I have one that is slightly darker red with black feathers here and there in her wings and tail. She is beautiful, but not what I would expect out of a golden sex link. Any ideas on her actual breed? I purchased from IdealPoultry.com. She is medium sized bird. Of all, she is the one that shows the most aggressive behavior towards people (which kind of pisses me off). When she sees me coming to try to grab her she will puff out her chest and jump (almost straight up). She doesn't get handled much b/c I don't really like to piss them off for no reason. I have 8 other hens to pet lol.
