I will have to agree with you, not because I want to, I have to. I would have had this done if it was a safe medical procedure but it is not. After checking with my vet, who had tried it once on one of his wife's roos & it was not successful. He said the testes were extremely hard to locate since they are up by the backbone & the surgery took way to long & he lost the rooster. I then checked with the vet department at OSU, Okla. State University, & was told the same thing. They do not do it nor do they approve of the procedure for the same reasons that my vet had told me.....it is very unsuccessful.
I would have loved to keep my 5 boys out of a hatch of 7 but that is not possible. I can't have 6 roos & 4 hens. I am so attached to them & they are so sweet, so I am trying to find good homes for them. I have 2 placed. So I can only hope they will be loved & took care of by someone else as well as I love & take care of them. And it will probably be a long time, if ever, that I hatch out anymore.
In mammals spaying & neutering is essential & neutering males that will never be used for breeding is doing the responsible thing. At well over 1 million dogs who are put to death every year because there are not homes for them people should be responsible not to let this happen. It does alter aggression in dogs but more importantly it would save the unwanted from being put to death. It does alter aggression in horses as all of my performance horses were geldings & I wouldn't have had a stud horse on my place.
