I have one of those big colorful, metal rooster sculptures with rebar legs out by the coop. Like this, but he's in red, yellow, white, black, and green:
I call him Gregory Peck.
The 7 Biddies are:
Aretha
Agnes
Blanche
Clara Cluck
Dorothy
Miss Prissy
Olivia
When I finally get 2 more, they're going to be Edwina and Muriel; they all sound like old biddy names to me.
