Ohhhhhhh noooooooooo if I go by this. .. one of my four week old giants is a roo!!!! The one with the big tail has started growing a yellow comb. Similar to a photo above.
Great photos and information, new to JG's..so far not sure about them. They peck really hard! I do have one that has a comb that turns really red when he comes after my hand..really hoping 'she' is a 'he'. The two others combs are dull, off yellow/black.
