I am not suggesting such a proceedure has application for anyone in my situation and my birds, rather I was trying to relate the complexity of behaviors and the role of vocalizations. Also when a rooster is a threat to his own offspring, the keeper needs to re-evaluate husbandry technique since I typically see such poor behavior when management is botched. I am reasonably familiar with challenges of keeping mixed sex groups of poultry in urban settings having done so while in college. Present interactions with such urban poultry enthusiast has made it apparent many are also interested in behavior as well occasional opportunities for birds to free-range forage the back yard. The induced voice change will impact the interactions of modified birds with others which should at least be considered. Otherwise it could be like using a castrated animal as brood stock.
