Problem: I lost my buck awhile back, and can't find a White New Zealand buck to breed my White New Zealand buck to. Every one wants to sell me a Black New Zealand.
Response: In Rare Breeds we run into this issue with shortage of breeding stock. If the BNZ has good body type, breed to WNZ and save a color cross buck to grow into a breeder. The color cross will have one white and one color gene. When 5 or 6 months old you can breed the young buck to a White doe. You should get half White and half Color rabbits in the litter.
So if you bred a BNZ and a WNZ today you could have a new litter with WNZ in 6 or 7 months with some color cross for the freezer.
Save more than one color cross buck and keep checking in case the Sex Change Fairy visits your rabbitry.
Have a good day!
