I just picked up six barred rock babies yesterday (to replace four cockerels I now realize I have). I just named them today, after characters from Game of Thrones.
Arya
Nymeria
Sansa
Catelyn
Brienne
Osha
With my 4 week old Barred Rocks, I was trying to follow the theme of Greek goddesses, but then I was ending up with cockerels, so I only kept two Greek names...Athena and Zeus (the cockerel I'm keeping). The other ones ended up with silly names...Pixie, Boring Girl, Boring Boy, and Brave Girl...three of those ending up being cockerels.
