Still it's an excellent and useful skill to learn. It improves the quality of chicken.Caponizing is a pretty safe procedure… for those who have a lot of practice and have done it many times before. For someone who is doing it for the first time, even a vet, the surgery can be very dangerous, and if done incorrectly (everything isn’t removed), the rooster will still be able to produce testosterone and do normal rooster behaviors. Assuming the vet doesn’t have much experience with doing this procedure, it will be very risky for your cockerel.
