Malocclusion Problem

We encountered a malocclusion or misaligned teeth problem with just 1 kit from among the 1st and 2nd litters of my original stock of Chinchilla doe. The kit could hardly eat because of its protruding teeth, then it got thinner and thinner until we had to destroy it. The thing is, we did not notice this problem at first until the kit was about 3-4 months old. I told my neighbor Johnny ( he's the source of my breeding stocks) about this and he traced the parentage of my original Chinchilla doe but unfortunately, he already slaughtered the mother and father of my breeding stock and said that he did not encounter any of this malocclusion problem with his rabbits before. He advised me not to keep this doe with this malocclusion problem because it might show up again in the future. It's just that I did not want to destroy this Chinchilla doe because she is a good mother and I like her big sized body. Besides, I am only raising rabbits for meat and not for show rabbits so I decided to keep her. The third time that she gave birth, I did not see any of the malocclusion problem among her kits so I kept one of them as replacement doe. I also encountered this malocclusion problem with 2 kits from the first litter of the New Zealand rabbit. When I re-bred her again the second time, I did not see it in her second litter which happened to be just one kit. I was not able to take pictures of the rabbits that were afflicted with this malocclusion problem but I did find some free images on the net to show you what it looks like.
