at what age can I begin breeding my new zealands? Also, is it ok to breed dads with daughters, mothers with sons? I read different things about these questions on the net.
You should breed them at 5 to 7 months old. Or when they are at least 6 pounds
As for inbreeding...you should be okay breeding father-to-daughter and mother-to-son. Just don't breed brother and sister unless the father or mother is unrelated (step-sibling).
Inbreeding is important when creating your own breeding line.
Hope this helps!
