How old is too to castrate a lamb?

There is no specific age at which it is too late to castrate a lamb. However, castration is typically performed when lambs are between 2 and 4 weeks of age. This is because lambs this age are less likely to experience complications from the procedure and they will recover more quickly. Additionally, castrating lambs at this age will prevent them from developing the secondary sex characteristics associated with intact males, such as a strong musky odor and aggressive behavior.

If you are considering castrating a lamb that is older than 4 weeks, it is important to talk to your veterinarian first. They can assess the lamb's health and determine if castration is still a good option.
