So rabits are just supossed to multiply naturally. My husband has been trying to raise bunnies for a year and a half with no success. We got one male, one female to start with (I think they were New Zeland) They were both of breeding age and never got the job done. Several months after we got the pair we found the female dead in the hutch. There was no outward signs of the cause of death and thought she may have had internal problems and that was why she did not get pregnant. So my husband got 3 new females that were 8 weeks old at the time. The girls grew up and are 9 months old now. (They are a New Zeland California cross). At 6 months of age we introduced our male to them, one at a time for a month at a time. No bunnies. We figured our male was a dud. We replaced him with a lop cross. The lop cross is trying his best to mate with our girls, but I think they may be too large for him. He tries and tries and the girls even mount him! What are we doing wrong?
