When I got my silver wynadotte hen, I wanted it to play off of the word silver. I name most of my chickens strange names, and most of them come from a strnage source. For my silver, I got her around the time we were going over the periodic table again. AG is silver, and the french word for it was Argent. Well, That sounded a little mannish for my girl after a while, so I changed it to Argentina to sound a little more feminine, not caring that you could find this name on the map (I had a Duck named Denver). Then I became lazy and just stuck with Argentine.
I typically change my chickens names if I forget them or if they go through the above process. Typically with RIR's, I just call them phoenix birds, fire birds, or red birds unless one starts to stand out. I started to call one fluffy, because her feathers have just started to grow again on her backside no thanks to a rough rooster. Then I changed her to Mey Rin because she tends to follow me and I have fallen in love with that name. I went through I process to get my two new Hampshire hens names as well. They were friendly, and their feathers reminded me of the sun, so I though "Rise and Set"... then I revised them a bit and they became "Riza and Zetta"
As for Roosters, they get special names since they're easier to tell apart. I've had Aristotle (Americauna mix), Galileo (which turned out to be a hen), “The Boys”-- 2 of Ari’s sons (mixed with a yellow buff orp), Argo, and Caesar (Were supposed to be Americaunas but I should have known better to expect anything from some large corp... they're white/pale yellow with brown specks on their wings). I'm getting a 10 week old Black and Copper Maran in a few days and although I wanted to go with a french name, I've found myself leaning towards Greek myth names. I'm thinking Apollon (Apollo for short), Helios, Hermes, or Prometheus. I've seen his pictures and he is a handsom devil.
Other names that I have used are Ku for my Black Sex link (Ku is the name of a crow in a japanese manga and also the sound for the hiragana く which looks like a bird beak).
Gold for my gold wynadotte (not a creative day for me) Iza (Eye-sa... because I used to call her "eyes" because she's an astralorp and they have such huge eyes!) I've had a small black bantum who's feathers shimmered green so I called her Kurohime (Black Princess in Japanese). I did call one of my RIR's Rot (sounds like wrote with a rolling "r") which is just red in German.... Depending on what class I was taking at the time, if I heard a word I liked, I used it.
I had the strangest names for my ducks... In the 4th grade, I could only come up with Seashell and Wave... then I got Denver and Diane, Coal and Shadow, Spot (because he was a pekin with a black spot on his tail freathers) Pyg (Pygmailan) and Freebird, who was a wild drake who was hanging around the duck pen one day and she just strolled on in with the rest of them, She never left even though we let her out everyday for a month. she was so sweet for a wild duck, made me wonder if she hadn't been raised by people and just stopped at my house becuase of my black and white duck.
So yeah, I have strange ways of coming up with strange names ^_~
