Hi everyone, new here, and new to having chickens. Appreciate this website as it's been helpful in building our coop and researching chickens in general. I'm hoping this group can help again. We have four chickens, two amber links, two is a browns. They range in age from 9-11 weeks. We're concerned the one of the amber links is a rooster as it has a much more pronounced comb and wattle than the other one. The second barely has any comb at all. Of course, the one we suspect could be a rooster is also largest of all four and atop the pecking order. Picture attached of both ambers. Any help is greatly appreciated!
