Such a fun question!
We have three hens:
Light Brahma named Lucy
Buff Orpington named Buffy (not the most creative, but she is just such a puffy buffy girl)
Dark Ameraucana named Patrick. Yes, she's a hen, but it just suits her perfectly.
My rir roo is named alejandro
my rir hens are fantine, cosette, bunny, twinkie, lil' debbie, and peeper
my americauna hen is named pippa
some other names I thought about are habenero, jalepino, eponine, and pedro
