Hi all, I have 3 week old chicks, but I'm unsure what breed or sex they are. I need to know the sex because my local ordinance doesn't allow roosters. The distinguishing factors to me are the dark grey legs and kind of unique comb (unsure here.) The combs look different in each image, so I'm wondering if that's an indicator of sex for this particular breed of chick? The second image looks more sharp and pointy compared to the more rounded comb of the first image. Would appreciate any help on identifying breed and/or sex for these chicks. Thank you!
