I tend to get to know my critters before I name them, as I like to give them names that suit their personalities. It's probably a good thing that I never had human kids, as I would've been the crazy lady with a nameless three-month-old infant. "But, he hasn't named himself yet!"
At any rate, thus far only one of my girls has an official name - sassiest Dominique is Miss Thing, because she's a ball of feathered attitude. My biggest BO is starting to look like a Mrs. Beasley to me, so I may be down to twelve nameless chicks soon.
So, were I naming in sets, here are a few I'd consider using. It'll quickly become obvious that I'm old.
Ladies only:
Parsley, Sage, Rosemary, and Thyme
Crimson and Clover ("over and oooover...")
April, May, and June
Ginger and Mary Ann
Daphne and Velma
I'd also like to throw in another vote for Laverne and Shirley, as those are great!
Pairs:
Captain and Tennille
Donny and Marie
Captain and Mrs. Muir
Luke and Leia (or, alternately, Han and Leia)
Luke and Laura
Dudes only:
Bo and Luke
Roscoe and Boss Hogg
Apollo and Starbuck
