yes,
in the wild hamsters don't have plastic houses, so they dig, like a rabbit or a mole.
I would advise that you just leave the hamster as it is, and check if she is eating and drinking as well as exercising.
Rabbits burrow to get shelter from rain, snow, and hail. They also burrow to get away from predators.
guinea hen
yes but only if it is frightened or just sleepy
The adult female is called a guinea hen.

Yes and fast
guinea hen
guinea hen
not particularly, there are many female and male guinea pigs
Actually rabbits an guinea pigs are fine together. But maybe the female guinea pig is felling lonely being the only kind in the cage. Or maybe its because the rabbit just doesn't like the guinea pig. If it's possible you can try getting another female guinea pig or separating the the guinea pig and rabbits.
No. There must be a male and a female for the guinea pigs to have offspring.
No! It is not possible without a male Guinea Pig.
