Naming birds is so much fun!
Sometimes I change my chickens names because their personality changes, or a pullet turns out to be a secret rooster. For example, Vanda turned into Vick and Shirley into Sher Khan (Khan for short). Prince turned into Princess, but poor Flo got to keep his name, even when he turned into a rooster. LOL.
Dominator (Domni) is my barred rock rooster.
Multiple names for one of my chicks include Secret (he was an extra hatchery chick), Long-legs (he has incredible long legs), Chapman (he looks like he's wearing chaps), and Eclipse (if he is a Dark Brahma, which I can't be sure of)
Sebbie also went my Saprano (he was loud as a chick), Dottie, Mr. Dottie, and Sebright.
I have an Acorn (he had a Chipmunk pattern), Liberty, Cowgirl (she looks like she has chaps also), Sedgewick (Sedgie), Yosemite, and many others! I even had a Smaug!
Appearance, cool names, breed, behavior and personality, and whatever I am interested in at the time are what inspire my chickens names. Bubs even got her name off her breeds code (she was a straight run Buff Brahma, so her code was BUBS).
