It's not very creative, but I named my Buff Orpington Honey because she's the color of .. well, you get it.
Since Orps are named for a town in England, you could go with British names for the girls. Think of characters from the Royal family or Downton Abbey. If I had another Orp, I would likely use Bronwyn, which I've always thought sounded both British and distinguished.
It is so much fun to name new chicks. It can be challenging as well. We pick a theme and then the names seem to come more easily. The theme we used for our new chicks this Spring was famous circus performers.
We had a Buff named Butterscotch I also think it’s fun to pick names within a theme. My theme for my newly hatched duckling was “P names:” Pip, Pongo, Puddles, and Pallas. Best of luck with your flock!
