Geld him early! With some colts it really is necessary and you can usually
see a difference withing a week or two. Contrary to what some people seem to
think, it doesn't hurt their development at all - helps in fact because you
are not having to get after them as much and they actually grow up bigger. I
had many colts and have gelded anywhere from 3 mos. to 3 years depending on
behavior and need.
