I am also worried about their bond being broken as I wasn't aware of this. What would you advice then for summer and Skye, given that the new set (new hutch and permanant run) up should be ready in a few weeks. Would you suggest spaying them before they move in? And what about recovery? How long do they have to be separated? They are both 2 years old and I am so worried that their bond will be broken.
A bond shouldn't break that easily. They should really be allowed to recover together (I did this with my pair) and certainly in the aftermath of an op they should be too woozy to fight. However if there are signs of aggression you can allow them to recover in pens that are side by side with mesh to separate them. They will still be able to see each other and smell each other. Recovery should really be indoors on soft carpeting or blankets./ No spiky hay or straw to poke shaved tummies. As such I would spay them before moving them outdoors. Hormones may take quite a few weeks to die down and aggression with it but usually it is much quicker than that.
About moving outdoors, make sure the weather is warm, not damp and cold as rabbits who experience a sudden change in temperature can develop respiratory diseases such as snuffles. The rabbits will need time to become acclimatised to the temperature change so let them play outdoors for short bursts (increase by a little each day) in the run up to the move outdoors.
In order to strengthen the bond you can also give them a soft toy each which they can cover with their scents and then swap the toys so each rabbit gets used to the other one's scent. Another good trick scoop up some poo's from Summer's litter tray and put them in Skye's and vice versa. They should need a week maximum to recover before being allowed to play/free range together. Bunnies come round amazingly fast from anaesthetic and you will probably have a hard time stopping them exerting themselves :lol:
You might find they become more affectionate with you after spaying too. And they should litter train easier if they are not already self trained. Also destructive behaviour should decrease.
Regarding the thread you found, a lot of the info is old, replies date back to 2004 and new things are being discovered about rabbits all the time, the species is not fully understood yet so I would go on the latest info available. There have been several leaps forward in rabbit medicine but prevention is still the best method. I can only re-iterate that as someone who knows the species well, neutering is one of the best things for peace, harmony, temperament and health.
By the way I think you have the right instincts and you are certainly asking the right questions. Its obvious and lovely how much you care about your bunnies. Keep asking questions, its the best way to learn
They are lucky bunnies to have you as an owner.
Just wanted to add that if you look at my signature you will see five bonded pairs, all neutered. One pair have been together for 10 years and not a cross word between them. One pair are newly bonded boys, both middle aged and totally mellow due in part to age and having been neutered long ago. So as you can tell I'm a strong believer in neutering. Without it my two boys would have lonely for a long time, maybe forever.
