Now he would charge more - that was about 15 years ago. But still worth it for just a couple of goats. We practiced on a couple of early buck kids first, then did around 50-60- doe kids in kidding season.
The urethra feels like a piece of thin (1/8-3/8") plastic tubing. It runs between the testicles and the penis. Familiarize yourself with the feel several times when petting those adorable goat kids and you will recognize the feel when you band. Oops, that doesn't sound very nice. . . .

Anyway, watch the kid carefully afterwards and you should see him pee. If he can't pee and his belly starts to swell in 24 hours, cut the band, massage the tube to get the blood flow back into the urethra. Then reband. If in doubt while banding, cut the band off and start over - bands are cheap. Once you get the hang of it you will automatically feel for the tube and no problem. And remember it is only once a year because you can band all the buck kids at once - as long as you do them by 2 months.
I would check to see if you have a livestock auction anywhere near, call and ask if the goat kids go to ethnic buyers for slaughter. If they do, save yourself time and trouble and dump the bucks at the auction at 2 months old without banding or disbudding. I banded and disbudded before taking the kids for years until I found out that the ethnic buyers did not want disbudded and banded. They actually paid more for them without disbdg and banding, and wanted them at 2 months! Yay! Saved me time trouble and milk which I needed, and brought a bigger check.
I prefer selling for meat instead of pets. A lot of pet owners buy "cute", lose interest in full grown, don't trim feet, etc., and often call you up a year or 2 later and want you to buy the goat back. (We all have stories about that.) Meat buyers are
repeat buyers.
