K--I am stealing that name. My new peep shall be named WILLY!! ha ha.
I am thinking I like Ginger. Does she look like a ginger? My Welsummer's name is Comet. I got her for X-mas. My son named her. Do you have kids? Ask them, they seem to always come up with the best ideas.

Being a newbie I wasn't sure what a Welsummer chicken looked like. I did a search and see they were originally bred by the Dutch. I don't have a particular suggestion but if nothing sounds right from the suggestions you get, maybe try this site I found full of dutch names and their meanings: http://www.babynology.com/dutch-girlnames-a0.html
Good luck, I look forward to hearing what you name her!
