The two that really bothers me is "Abigail"and "gracie"....might be roo, but at that age should have a lot bigger comb...also Citron Hamburg pullets do get combs and wattles that look just like your pic....so tough call
One day I noticed that Abigail's legs were a lot thicker than Charlotte's which just about caused me to faint. Abigail is also the dominant one of my little group. As far as Gracie, I agree that comb is very red. Behavior-wise she is very comfortable pretending she is Agate's mother. She lets the little one pick food from her beak and she will roost such that Agate can snuggle under her breast. Would a roo do that?
