Fourteenchicks, what if you went to sleep and woke up and you could never have children ever again? Or you woke up and your BALLS were missing? Imagine if that happened to your husband, wife, daughter, son... This is what we do to dogs, cats and even rabbits every day. It is strongly encouraged by most groups including the biggest animal rights groups that you do this to your animals and if you don't then you are a bad pet owner!
Luckily we know through many cases where animals have had to have limbs or other things amputated or surgeries to remove organs, etc, that they do not express mourning over the loss of a typical function... Which is why spay/neuter is considered OK.
There is no months of sadness and sorrow that humans experience when they wake up and suddenly find that they have lost a part of themselves. They simply wake up and are happy to be experiencing life. Most dogs will not even notice the limb is missing except to have to find a new way to move. They work to find a way around the disability rather than mourn it. Similarly dogs when debarked will continue to bark, and may try even harder, because the goal is to make sound... But they're not mourning the loss of the voice, they are just trying to make sound still, much like a dog who has 3 legs will try to walk still. Why people think determination to succeed is mourning I am not sure, but it isn't. Animals are not quitters and they live in the moment, enjoying life for what it is.
I think with the testimonies of the people here, we know that the goal of these roosters crowing is simply the act of crowing... Not to produce a loud sound. The people on here have said that the roosters proceed to act totally normal and do not become obsessed with trying to make sound like some dogs do so that points to this being the case... Especially since not a single rooster yet has become neurotically obsessed with crowing. Even if the odds were low you'd think we would have seen ONE by now. So it is the act of crowing, not the volume of the crow that is satisfying. That makes sense since chickens have very little brain anyhow and a rooster that has a naturally quieter voice will still crow the same amount as a chicken with a loud voice.
I have some kinda pricey chicks growing out right now and I suspect 2/3 are roosters... I am strongly considering having one of them decrowed so I can have a rooster in my flock. If I have the money for it I will contact Dr Dave to have this procedure done. As someone who keeps chickens because of a concern for the welfare of the animals that provide me food, I feel like this is a totally acceptable procedure when taking the welfare of the animal into consideration.
