How will I know if it turns out to be a roo? These are my first chicks. I have a Duckwing also but it is definitely a roo. The grey Cochin had a comb way before the Duckwing but the Duckwing grew fast and turned red and already has waddles starting. My other 2 are a Tolbrunt and a Golden Laced and are definitely hens. This grey one is the one I'm confused about since it does have a large comb but it isn't turning red... It does have a shorter and less pronounced tail then the other one though.
