* Rabbit breeds: Some rabbit breeds are known for having black fur, while others are not. For example, a Dutch rabbit is expected to have black fur, while a Himalayan rabbit is expected to have white fur with black points.
* Genetics: Even within a breed, fur color can vary depending on the parents' genes. If both parents carry genes for black fur, it's more likely their offspring will have black fur.
Here's what you need to do:
1. Know your rabbit breed: What breed are your rabbits? This will give you a starting point for understanding what fur colors are typical.
2. Consider the parents' fur color: What color fur did the mother and father rabbits have? This will help you understand the genetic possibilities.
3. Consult a veterinarian or rabbit expert: If you're unsure about the normality of your baby rabbits' fur color, talk to a qualified professional. They can assess the situation and provide guidance.
Remember, a variety of fur colors are possible in rabbits, so don't be alarmed by black fur! It could be completely normal depending on the breed and genetics involved.
