If you are looking for advice I would have some.
First what does he want them for? Meat, dairy, pets, mowers.
Well they do not mow grass they will eat tall weeds and shrubbery. Stay away from Nubian goats, the ones with the floppy ears. They are very high strung. If you are looking for tame and easy to manage, trim hooves, etc, get bottle fed young ones. The Swiss breeds are all good. Gentle. We dehorned all our baby goats so the horns don’t grow. Safer for everyone and if you use a dehorning iron when they are just starting to grow, easy. I was goat superintendent for the county 4h fair for 5 years, saw more goats who did not have good health care than the flip side. Plus we raised our own for 25 years.
Yes, you are my Go-To Gal for goats. I think he wants them mainly for pasture mowing more than anything. Let’s see how he does as a ‘Chicken Daddy’ first, LOL!
