You might consider a No Crow Collar which you can purchase from My Pet Chicken.
It acts like a dog collar around the rooster's neck preventing him from swelling up the pocket of skin at the base of his neck with air, like a bagpipe, which is what produces the volume.
With the collar, his crow comes out more of a muffled squeak.
It is important to monitor the rooster and check regularly to be sure the collar remains positioned correctly with no obstruction or irritation.
I have used one very successfully on my rooster for almost 4 years. You will need to replace when frayed or bunched.
Collars allow many roosters to lead happy and productive lives but quietly.
