My new rooster "Iago" is very aggressive. I've tried all the usual tactics and so far the only thing that works is a water pistol. Am I going to always have to be "packing a pistol" (actually a toy ray gun) or is there another method? I know he is only doing his job and hope he'll be a great guardian of the girls when the local foxes, hawks and fishers come a calling, but my concern is when I need to have some one else take care of the hens. Thoughts?
