Humping isn’t bad tho. It seems that people never want their rabbits to hump ever, but it’s going to happen. I honestly think that it worries us humans more than it does the bunnies. It’s a show for dominance, and it is very common. You do not want them to hump “the wrong way” because the rabbit underneath can bite the humper’s genitals resulting in a nasty wound. You do not want the humping to continue longer than maybe 20-30 seconds. At that point, try to nudge the humper off. If the rabbit being humped is accepting and always has the option/space to run off, it can be allowed. The issue at this point is with Wooly being so newly neutered.
There is humping in my pair every single day. They have been bonded for almost 3 years. For some pairs, this is something that is always present. Others will establish dominance and then eventually stop the humping, except maybe on the rare occasion.
As far as your husband, if he thinks he can do a better job, by all means, allow him to do the research required and sit for hours and hours supervising the bunnies interactions. This way YOU can lay down, have a glass of wine, maybe read a good book…? Sounds like a win-win for all! LOL!
But in all seriousness, he needs to recognize that there is no guarantee with bonding bunnies. Some bond instantly, some take months. Some DO NOT BOND and can never live in the same habitat. For every member we have with a bonded pair, we have another member with two buns who, despite trying every method, would literally tear each other apart given the opportunity. Hopefully he knew this was a possibility. Let’s say you can not bond them. Will he be okay with having them live separately for the next 8-12 years, or would he want to rehome one or the other?
