I acquired a flock this last week, including 7 hens, 1 rooster and 4 chicks that are about 9 weeks old. I am pretty sure I have 3 of a kind, but I'm not sure if they are boys or girls. I am hoping girls but they have a larger comb than the 4th one. I was told the chicks are Amerucana, but I think they are just EE's. What is the best way to tell, can you help. My threesome all have red heads with a larger comb, the 4th has black feathers on its head with a very small comb. The black is at the bottom of the picture. Here is a better view of the comb on one of the reds, they are all about the same.
