I have 11 Chicks who are about 6.5 - 8 weeks old. 1 barred rock, 2 welsummer cockerels, 1 midget welsummer pullet, 2 light brahmas, 2 columbian wyandottes & 3 Easter Eggers. Everyone should be a pullet except for the two welsummers I hatched. One of the EE's could be a cockerel, but so far nothing screams male. Here is a picture of them (can't see all of them) after I put them out in the hen house. I have one welsummer chick (presumed pullet) who has just never grown. I feel bad for her, but she seems to get along with the rest of the chicks. I thought about putting her in with my 3 week old welsummer pullets, but since she gets along with her group, I left her with them. Here she is with one of her hatchmates. Remember, they are about 6.5 weeks old. I'll leave them in the hen house for a few days to 'tell' them where home is. By then the outside coop will be done and they can be released.
