Will have a quick chat with my wife, suddenly realized this would mean reusing an old indoor cage here, until we could get the girl to the point we could put in with our girls.
Also, no nookie between the bunnies allowed, we don't have space for babies lol.
Update..
We are a little concerned we could find ourselves with three cages as we can't move the girls all in together straight away. Long term the suggestion would be neuter the boy, that way he and her can share a cage (it's actually the recommended mix of rabbits -females are the more dominant).
My wife has a cousin in Karamea that could be interested though...
Sorry, about the cold feet, just need to really work it out a bit more, and basically running out of time for us to be an option.
Another option would be to bring them to an SPCA that has a no kill policy I.e Wellington doesn't.
