Hi Farai
The Kalahari Red goats are not common in Zimbabwe. As a result there is just a few Kalahari Red goat studs in the country, where you can purchase them and get guidance. One option is to purchase directly from South Africa from reputable and established studs for guaranteed best genetics for your project.
In Zimbabwe you can contact Mzilikazi Kalahari Red Goat Breeders on +263 772391699. and Zviko Farms on +263 71 932 9640 for assistance and purchase options.
I have included in this response some website links of resources that may help you in your endeavours. The list is by no means exhaustive.
