bonding advice

ok i have 2 rabbits that i would like to bond but i'm really don't know how to go about it.
Also today charlotte jumped into the run with dave ( the 2 i want to bond) there was no fighting but he has humping her head a bit and a bit of chasing other than that they ignored each other.
So how do i go about bonding them??
The only neutral area i have is my downstairs toilet but they both normal live outside.
Help please.

On my website (link in my sig) there is an article about Bonding or Bonded bunnies which may be worthwhile reading.

Also, if you search Janice-ARCs posts she is hugely knowledgable and you would also learn a lot from her posts too.

great link thank you
