I agree…. take a look at the top green bar. Bunny info-Bonding info. There is tons of good information there.
1) Make sure both are neutered (and let them heal for at least 3-4 wks before you start bonding)
2) Find a neutral territory (bathrooms are usually safe bets) and then section off a small area (the tub works great, or make a pen out of NIC cubes 3’x3′ ish)
3) If they dont get along in neutral territory you may have to try stress bonding. Some examples include car rides in a small cardboard opentop box, a ride ontop of the dryer in a box or basket, running the vacuum cleaner or other load appliance while they are in the neutral area, etc. This will help them to feel stressed out and reach out to one another for comfort. The point is for them to be uncomfortable alone and gain trust in one another.
4) Know the signs of agression and stop the bonding session before it escalates to that. Watch out for nips, lunging, grunting, agressive chasing, etc.
5) Bonding takes time!! Some buns like eachother after a few bonding sessions while other buns take weeks (and sometimes many months) to form a relationship.
**Humping is NORMAL.** It is how they assert ther dominance. Over time once they have worked out an agreement on whos dominant the humping will die down and with most buns it will be rare to see them hump very often again. In order for their relationship to work both bunnies need to be okay with their place. Usually one is dominant and the other submissive. If both buns are okay with their roles then their bond usually is easier… but if the “submissive” one isn’t willing or the dominant one is too much of a bully sometimes it takes longer for them to work out how the will live together and love one another. Let them mount for 10-20sec, sometimes it helps to pet the submissive one and tell him its alright, after 20 sec push the one on top off. I usually then would make them sit together so their heads were touching and rough pet them switching hands so that they got eachothers scents.
When I was bonding my two boys I did a lot of reading of the bonding forums. Look at the photos and watch videos that people have posted. It really helps to see and learn other buns body language so that you can pick it out in your own buns. If you provide a more detailed story of your bonding area and how the boys are reacting to one another there are lots of bonding experts on here that might be able to decode the rabbit behavior for you and give better suggestions of techniques to try!!
Welcome to the forum and best of luck bonding your two boys!!!
