I only have the one cock bird and 2 hen's.. here on loan.. .. he has no competition from other cockerals so he does not crow that often and when he does it's only for a short time..i live in a built up area and ive had no complaint's to date..i also have 4 trio's of Japenese (Cotunix) quail and they are louder and more noisy than the serama.
