Update: Gender of 4 week old blue cochins??

[Stiggy]

She does look like a light black, but she could also be a really dark blue black color. Reddening of the comb for males depends on age and isn't always a definite . once they are fully feathered we should be able to tell who is who gender wise

Thank you! I'm glad to hear it isn't definite
