There are many female-specific colors, here are few examples from pictures I found on the Internet (I do not own any of these):What are the female-specific colors? Learning something new...I am keeping a close eye on a grey EE that I keep thinking may be a cockerel, but from what I've learned could just be a larger female. Maybe week five will start showing more evidence. Thanks so much!
And here is a Black Breasted Red Old English Game Bantam female, displaying the female-specific color version of Black Breasted Red, which is completely different in appearance than the male version.
