I have 9 EEs (3 roos), 9 BOs (2-3 roos) and 3 BO/W x that are all about 14 weeks old. One EE crowed at 6 weeks but the other 2-3 still haven't crowed. The BO/W x roo crowed at 10 weeks and he thinks he's the alpha, chasing everyone, pecking the backs of heads etc. So, 2 roos are crowing and 4 or 5 aren't. Is this just normal pecking order behavior? The two breeds usually stay away from each other when free ranging but get along really well in the coop. It's not a problem, just a curiosity. What do ya'all think?
