letter about New Zealand rabbits

Question
I have rabbits that were born on the 19th of April and I was wondering what the age is that you are supposed to sell them at? I noticed 1 of them tried mating with  another one today is that the sign all of them are ready to go :)? From Jackie

Answer
The act of mounting is a sign of dominance, not just a method of mating.  I usually wait until my litters are eating and drinking from mom's food and water well.  A good age is about 6 weeks.  They can reproduce at about 3 months so it would be wise to separate males and females before then.
