Hello all, I have 3 males and 2 females, all hatched around mid June of 2016. Of the males, 2 are IB and 1 is a Spalding. Up until yesterday they had all been getting along just fine. The Spalding male was harassing one of the hens terribly, chasing her around and at times standing on her back. Are they still a bit young for attempted mounting? I have them separated at the moment to keep her safe. Does anyone have any idea why the one of the males would be acting so aggressive towards one of the girls at this age? and this far outside of breeding season?
