Quote: Well like i said I'm no expert, but they just don't scream roo to me! I know I had a lot more chickens than you did when we first got chicks, but mine chest bumped and sparred ALL.THE.TIME. From day 1 those girls were feisty! One of my Buff Orps even stood her ground at only 10 days old to my cat who whacked her while she sat on the edge of the brooder! I'm pretty sure that was Lucy, and right now she's towards the top of the pecking order with my dozen girls.
I am going to say Latte is definitely a pullet. Rocha has nothing really that screams cockerel to me, another week or two and should be sure. Yes post pics of Cocoa and Blackie. My 2 EE girls(11 weeks) attack each other like hawks, they are trying to figure out who is gonna be #2 in their sub-flock. Amber(GSL) is soooo #1, I think when she is big enough she may just be very high or top of order for whole flock. She already jumps in with the big girls for raisins. The EE's wont come near the big girls.
I would really give then a couple more weeks to be sure. If those combs seem to get redder overnight then I would worry. But you can convince yourself of one or the other so easily during the early weeks. It messes with your head, believe me, I have been there!
