I am starting to have success getting hens and my ROOSTER to be quiet! Look into clicker training -- reinforce their quiet voices and silence. I even managed to get my rooster not to crow this morning, and I only started training 4 evenings ago. It's standard animal training techniques reinforcing with treats.
There are videos on it on YouTube, googling clickin chicken, googling chicken training, operating conditioning. There's even a book called Clicker Training for Birds.
