"Do you think these indicate a gender difference or just how they inherited the comb types of the parents? Any other clues as to sex ID at this age or do I just need to be patient? So hoping at least a couple are girls and lay olive eggs!" quote from mayhysong
maryhysong comb shape is never an indication of gender. The shape is determined by the parents shapes and since your parents Welsummer larger single comb and Ameraucana pea comb (?) have different combs styles each bird has their own variation of the mix. Nice birds BTW
Thank you Flower. I only thought the comb difference might indicate gender because when it first showed up around 8 weeks, it mostly looked like the two double ones were much bigger than the singles, so I thought they were roos. Been a long time since I raised any straight run chicks. It wasn't until the original owner confirmed the fathers identity and I looked at pictures that I realized the breeds have different combs and that it might just be differences in comb types. So happy to think they might all be girls.
