As a group.. mine are "The Demons" or "Winged Vermin".. mainly because of the way they'll storm the coop door when I open it

(Normally accompanied by me gently pushing them back with a foot, "Back! Back you demons! Back, I say!")
But each of my 10 hens has a name and I can tell them apart..
Arucana - Ariel (tall, slender frame, pea comb, and dark golden colored)
Wyandottes - Kerowyn (a bantam columbian)
Tabitha (a silver laced with "too much" black and a skinnier frame)
Anabelle (a silver laced with a plump frame and even ratio of black to white)
Australorps - Morticia (full comb on her head with a round end)
Wednesday (The end of her comb was notched.. suspect as being damaged by one of the other hens at some point)
Polish - Mikaela (white crested black.. she's the only polish)
Bantam Frizzled Cochin - Ms. Frizzle (black and white little puff ball of a bird.. can't be confused for any of the others)
Silkie - Stormy (renamed from Smokey after a near death experience as a chick. I believe her color is called "blue")
D'ulcce/Cochin cross - Polly (smallest of the lot, light brown in colored.. LOUDEST of the flock. Loves to sit on the highest perch in the yard and announce her presence. But she does lay, so she is a hen.)
