I have done some looking around on this and it seems like it just depends on the individual rooster. Alot of people suggesting a certain breed, but then someone saying their rooster of that same breed is very loud. bantams will be quieter because of the smaller size I know that. I liked my blue Jersey Giant. . very very large, gentle, does well in small flocks with various breeds, and his crow would be real deep rather than the higher pitch of the smaller roosters which in my opinion the higher pitch carries farther.
