This is Sandora, she is very talkative, but no crowing. Her waddle just showed up today. No crowing. I have a roo in the flock. No laying yet, this is my first flock of chickens. This is Sandora at 8 weeks. This is her sister coal at 4 months, the only reason why I am wondering if Sandora is a roo. Coal's comb and waddle are not as developed.
