I got my chickens when they were 8 weeks old, they are now 22 weeks. 2 silkies and 4 RIR. Well my silkies turned out to be roosters. The smaller of the silkies, Louise aka Lewy seems to be very aggressive towards the hens. He will grab the back of their neck and pull on them. He also will chase the girls around. My other silkie rooster, Thelma aka Theo does not act that aggressive. I don't know if I should be concerned or worried about Lewy being this aggressive towards the hens or if it's just a phase. All the girls seems to be fine and there are no battle wounds. Is this normal? Do I need to relocate Lewy which I really don't want to have to. HELP!!!!!
