I'm completely brand new to owning chickens, but have wanted to try it. I have four that are about 13 weeks old (bought when they were ten weeks). They were bought on the pretence that they were all female, but I'm begining to wonder about a couple of them. The two in question tend to have more of a strut to their walk; head and tail held high. I have also seen these two fighting with eachother on a couple of occasons ( no injuries fortunately). And the comb on one of the two in question is darkening faster than the rest of them. One male won't be so bad, but two will be a problem. My chickens are leghorn/australorp crosses, if it makes a difference.
