Hello! I'm new to owning backyard chickens and have read a ton on BYC recently (thank you to everyone for posting - really beneficial!!). I have 6 chicks from 4-6 weeks old and am pretty certain most are hens but there is 1 that I'm not too sure of - my black cochin (Ms. Frizzle). The farm I got her from was fairly certain about her gender and also noted that she was 6 weeks old. I have my doubts though (she is quite fiesty but not aggressive) and thus am looking to see if anyone has any thoughts?
