i have a giant australorp rooster. hes about 6 months old. Huge, stately, beautiful bird. before i got him the hens were sleeping outside, here and there. runnin wild. Now that i have him, theyre right next to him every night on the perch. he fends the ducks off long enough for the hens to eat. he definately lets his ladies eat before even going for the food. and he's an amazing looking bird. ALWAYS keeping a look out. every other bird is peckin at the ground, hes lookin around and up and down all day keepin em safe. you dont NEED a rooster, but why not?
