I cannot see well enough to say it isn't a straight comb, but you can tell on day old and up seeing it in person, the difference is actually quite obvious when compared to pea comb chickens."Olive" was purchased as an Olive Egger, but now I'm doubtful. Would those experienced with BCM x Ameraucana Olive Eggers chime in? She is 11 weeks old and has what looks to be a straight comb developing. I don't think it's a pea comb as my Ameraucana's comb looks much different. (I'm a complete and utter newbie so bear with me.) This bird would be a 2nd generation as per the breeder. The first generation was a BCM X Wheaten Ameraucana. I get it that all of those birds would have a pea comb, but should carry the straight comb gene. My bird is a result of breeding the F1 bird back to a BCM rooster. I understand the genetics, but I'm unfamiliar with what a straight comb looks like at 11 weeks. Is this a straight comb? Any reason, based upon looks, to think she is a he? The behavior has become more confrontational with the other chicks lately. It may just be natural pecking order, but I'm beginning to wonder about Olive's sex.
Thanks for taking the time to look!
If they were pure stock, the Ameraucana should have been Homozygous for pea comb AND blue egg genetics thus making it impossible to have anything but a green or olive egger chicken with a pea comb in the F1 cross. If the selection for pea comb and blue egg genetics wasn't very consistent in the parent "Ameraucana" stock, you cannot know what she might lay until she lays her first egg. Keep us updated though!
Your pullet color combination is my favorite color of chicken. Dark blue laced feathers with red leakage in the neck (idealy also the chest for me!) I think is just a beautiful combo. I am so excited to finally add blue feather genetics back to my flock!!
