Over the past few weeks, we've noticed some crowing in the wee hours of the morning. However, we can't locate the culprit, but we *might* have it narrowed down to one of two. I have two black "hens" that are supposed to be the same breed and age, but they have different comb and wattle development. Are they both Roos or just one of them? We know at least one of them has more aggressive behavior, but because they are far away when we notice the behavior, it's hard to tell which is which!
They are about 16 - 17 weeks.
