We have an Ayam Cimani rooster who takes care of his flock of 5 Australorpes, one Wyandotte and one EE. Whenever he mates with one of the Aussies, the Wyandotte attacks her viciously while the short mating ritual takes place. And SHE gets attacked by the EE whenever the roo is on her. I have not seen one of the Aussies attack another Aussie during the ritual. The Aussies are very gentle and will let me pick them up. The others are not like this.
Why the attacks during mating?
