I have 1 24 week white Silkie hen and 3 18 week old silkies and 2 are blue and one splash. I am pretty sure both blue are roosters. I have seen one of them mount and one crow but they look very similar so it's hard to know which is doing what. They have large combs. But the splash is the same size as my hen. It's a lot smaller than the blue even though they are the same age. It doesn't seem to have a comb yet. But it does have whispy head feathers. But I swear I've seen it mount and act aggressive to the roosters. What do you think on these 3?
