We have only BCMs and five sweetheart Roos but one meanie. He was from a real friendly roo and his offspring so far have not been aggressive. Can it be that Agro is not passing his bad manners on to the chicks ?
Seems to me I read somewhere that the temperament of the off-spring is determined by the hen. In other words, it would be mom passing on the good or bad manners to her boys.
