None, unless they should catch rabies from some type of vermin.
In or out of what? Their nest box? They should stay in their nest box until they are able to get out by themselves. Is that your question?
No. It takes a bite or a break in the skin. You don't know if what hit your leg was even saliva.
it is ok aslong as long as they are brothers and sisters and born in the same littler do not introduce any other bunnys until 8 weeks apart froom its mother and brothers and sisters
You should only handle newborn bunnies, if you absolutely have to. As in moving them to another cage while cleaning the current cage. But, you can handle them right away. Please don't, though, unless you have mommies supervision.
If the doe has been lost (died) the best bet is to transfer the bunnies to another doe or find a breeder with experience tube feeding. Feeding newborns by bottle is problematic and often ends up with aspiration pneumonia.
It is normal to find a rabbit's nest with fur from the mother. It is doubtful that this is a requirement for baby rabbits to survive but it presumably adds some protection.
Bunnies. Bunnies. Bunnies.
