I can't be sure, but I read it is illegal in the UK at least. I was mistaken as to how many places. Seems rather more brutal, reading about it. I've seen young pigs castrated and helped band calves as a kid. I don't really know why chickens would be treated differently.That is interesting that it is against the law - where many, many other animals are routinely castrated. Granted, most of the other animals have external testicles. But, castrating a slightly older bull is not a nice procedure!. (It they are too old for the elastrator, the vet literally crushes the 'tubes'. Or at least they did when I was a kid and we bought a 6 month old male 'calf'.
And how often are dogs and cats 'taken care of' in a not dissimilar fashion (though, under anesthesia and by a vet.)
Apparently there's a chemical option. But then you deal with chemicals in the bird you're eating.
