You have two options when fulfilling the husbandry manuals requirement:
1. You can look for existing husbandry manuals for your specific breed.
2. You can look for husbandry manuals on other breeds of the same animal and adapt them.
Many times, you won't be able to find a husbandry manual specific to your breed.
There are many husbandry manuals available from the AZA and other professional organizations which can be adapted.
