In my TSC all the Bantams are not sexed, so make sure you know what to do with the extra cockerels. All of the Bantam cockerels I got from TSC are in a Batchelor coop now and get along well.
The TSC employees didn't know what breeds I got, so I'm going to assume that yours won't either. Just post pictures on the what breed or gender fourm and find out there. I got mostly old English Game Bantams, red Pyles, silver duckwings and a lavender. One silkie, one black tailed white Japanese bantam, one minorca, two porcelain d'uccles and what I believe was a cochin who died within the first few days.
Some breeds are easily recognized, like Silkies who have extra toes.
I can't wait for chick days to start! I think I'll stick to sexed chicks next time!
