Originally we had names picked out before we got the chicks but ended up not naming them initially because we heard that they can die so easily that you should wait a few weeks. So we waited a little while to make sure they were healthy and they sort of grew into names. Little Brown and Big Brown (silkies), Little Grey and Gus (guineas), Zeke and Zeus were also guineas but they died. We have two white silkies but they still don't have definite names. We call them both blondie because they are still yellow chicks. Once we can tell them apart one will be Sophie. Our 5 bantams were named based on personality. There's Momma because she was the biggest chick and she seemed to care for the others right away. Cubby because he was a little black ball of fluff who looked like a baby bear cub. Another is Ruby (a cochin of some sorts) and others are Annie and Pippy (RIR bantams).
Thanks for the suggestions!
