First let them acclimate for two to four weeks with minimal handling. This allows them to get familiar with their new surroundings as they are probably WC and have travled from Africa-Customs-Importer-Wholesaler/Retailer-you. Start slow and five to ten minutes every two to three days. See how they react to your movements. Belly stroking after two months will start to calm them in a transe type. Never use fast movements or loud nosies they will bolt. Set up a routine with them and they will get more acclimated. Some take up to six months to realize they are staying home now.
