It sounds like Ginger is well ready to be fixed! That should at least help with the peeing everywhere, and the smell. You won’t be able to bond them until after the little one has been spayed and has had time to recover after. Rabbits can really change around the age Ginger is, when hormones kick in, and the little one may well do the same in a couple of months time! And things don’t settle down straight after the spay, either, that takes weeks.
I am currently in the middle of trying to bond a trio, two girls who may well be sisters, and one boy. One of the girls bonded to the boy pretty much instantly, the other girl has gone from outright teeth and claws, through the cage bars, to nips and haircuts. It will be four weeks tomorrow since both girls were spayed. She is going to take a lot of time, patience, and care, to have any chance of bonding her to the other two. From everything I’ve read, plus my own experience, a boy-girl bond is the most straight forward, but it does also depend on each bunny.
