Hello, I'm Dr. Bob.
You can find the first page of an article describing the operation you're seeking as done in peafowl, but unfortunately you'll have to join one of the sponsoring organizations to access the rest of the article. The article's first page is here: The operation should be identical in chickens.
Thomas Tully, Jr, in his excellent textbook "Avian medicine" states the following "Devocalization by cauterizing the tympaniform membrane is possible in gallinaceous birds but the surgery has risks and is not always successful and therefore not recommended." P. 33
You can read an interesting thread about this procedure here:
It would seem people are highly opinionated on this subject!
Alternative methods of controlling crowing using the manipulation of the lighting in a light tight coop (roosters don't crow in the dark), or containing the rooster during the night and early morning hours in a cage large enough to allow him to comfortably sleep, but too small to allow him to stretch out to crow seem more humane and less risky for the rooster.
If I may be of further assistance to you, please let me know.
