Is it just me or does anyone else find the Orpingtons much quieter & gentler than the Australorps? From the research I did, both are supposed to be quiet & friendly for a dual purpose bird. So I ordered 13 of each. So far, my Orpingtons seem to be much more docile & quiet. My Australorp roos are rough on the hens and crow constantly (at night - starting at about 3AM). Just wondering if this is typical; if the Australorps will settle down after they mature (they are 6 months old); or if I should plan on adding more Orps in the future.
