I own a large cochin rooster and his 5 girls, raised up from hatchling, one silkie rooster (5 months old) and he has 3 girlfiend silkies. raised from hatchling. Every one gets along so far. The two roosters are fine around each other. Each rooster have had their time to show aggression towards family members. My cochin rooster likes to at times, threaten my grown daughter and son but I'm the boss. The little silkie rooster is trying to intimidate everyone including me! I snatch him up and pet him everytime. I remind him I'm his mother. I thought silkies were suppose to be sooooo sweet. Mine act just like chickens. Of course, all come running when they think there's treats. Will he get a better attitude and at what age do silkies start laying and will the roosters inter breed.? That would be too funny.
