Most of my pullets don't have names because they look so much alike, especially the Black Stars and cuckoo Marans. The EEs do look different, but some of the differences are so slight that it's hard to tell. We did name our darkest, plainest EE pullet Kitty, and we have a BS that we call Floppy b/c her comb almost covers her eyes. Other than that, the other girls don't have names. Our cockerels names are Casper (aka Satan's Minion, aka The Feathered Demon, aka Dumba**, aka You Piece Of Crap Stop Skittering Up Behind Me Trying To Flog Me)- silver Lakenvelder; and our four EEs- Hannibal (head cockerel), El Jefe, Severus Snape, and Professor Lupin.
They all respond to "Chick chick chick chick!" or "Bock-bocks!"
