Most people band miniature goats, but when they're big enough, you can use other tools. It is possible to castrate older goats; over 4months, without much trouble at all if you use a correct tool.weeks minimum age, but if you plan to neuter them later then 6weeks, remove the buckling(s) to a separate pen from their sisters/dams. They can breed as early as 7weeks, so you have to be very careful.
Castrating your kids is an easy procedure. If you are squeamish about it, have a veterinarian or a goatkeeper friend do it for you. If you want to observe before trying it yourself, volunteer to hold the goat for the procedure. All of the methods require a helper to hold the goat. About a half hour before castrating the kid, give him one adult aspirin, 0.25 cc of Banamine (prescription only), or some white willow bark tincture to help prevent pain, and 1 cc tetanus antitoxin to prevent tetanus.
