Rusty our male lives at bf house as I have my own.
I could do the raising,spaying,recovery and waiting process at my home. Then do the seperate area pen for the recommended time it may take or more then slowly and careful see how the bonding goes and move on from there.
What about that ?
If you do get a baby, that would be the way to go about it. BUT... (and this is a big "but") you are taking a real risk that the two rabbits will refuse to bond. You have no way to predict if they will bond and the perfect planning in the world won't guarantee it will happen. It is totally up to the individual rabbits. If you are fine with the idea of housing the two rabbits separate if they refuse to bond, then getting a baby is just fine. If you really are set on finding a bondmate, then getting a baby is simply not advised.
This is the huge advantage over getting an already-fixed rabbit from a rabbit rescue: If the rabbits refuse to bond, you can exchange one for another. They work with you to ensure a bond.
I have personally experienced several bonding attempts in which the rabbits refused to bond. There are numerous others on this forum who have posted about their bewilderment at why their formerly snuggly bunnies are suddenly fighting viciously; or those asking why they having such difficulty in getting their rabbits to bond.
For those who have not experienced this, it may be hard to imagine. Seeing two rabbits viciously fight seems almost incomprehensible. I say this only to let you know that while some bondings can truly be a walk in the park, others are considerably more difficult and stressful, and some just will not work no matter what. The individual rabbits determine whether or not there will be a bond.
If you still decide on getting a baby (are fine if they don't bond) then I don't see any benefit/reason in that instance for Rusty to do any choosing. It would be meaningless since babies are totally different once fixed & grown so that any baby that is chosen would be unrecognizable to him anyway by the time it grows older and is fixed.
