Our flock began in May 2010. A few weeks ago I was given 3 Barred Rocks. They are so aggressive w/the girls. They are continually mounting them and then the loud, shrieking protests of the girls can be heard. Then, the feathers fly! My girls are going to be plucked clean! Oye! What do I do? Will the aggression calm down? Will the girls become accustomed? What should I expect? TIA!
