So I have a RIR rooster about 8 months old. He stared off as the quietest creature I have ever seen. He has changed in the past couple weeks and begins to crow at 4:00 a.m. and will not begin to stop until about 8:00 and then he starts to calm down a bit. He then will crow again non stop until my three hens are done laying their eggs. Just wondering if it can somehow be trained to crow less or is it just how he is and I'll have to deal with it?
