Hello, rabbits can do well on their own if you have a lot of time to give them. If you are someone who is not home very much, and can’t spend much time socialising with your rabbit I would recommend having two that can be bonded.
I had just one rabbit, but I am home a lot and he had 6-9 hours of free time outside his cage every day with me in the same rooms, interacting with him etc and just being around him. You can obviously have less time than this available and have it still be ok, I’m just home a lot and my work hours are such that it worked out well for bunny play time
If you are concerned about the trials of first time rabbit ownership, and bonding, you could always just get one rabbit now, and when you feel more confident with care, behaviour and handling etc, perhaps then you could look into getting a second one. Whether it’s a youngster that you get spayed yourself, or an adult that you adopt already spayed from a rescue (they also do bunny dates to see if your rabbit and the one you plan to adopt will be compatible). If you still want to get two bunnies, I won’t put you off doing so because it sounds like you’re getting yourself well prepared. From things I have read, bonding can be both a breeze, and an absolute nightmare, and you never really know what you’re going to get. I just like to let people know that things may not work out from the get go so that they don’t go into things with unrealistic expectations.
At the end of the day, if it worries you and you don’t feel quite right about it at this stage, by all means just get the one, it sounds like you’re home enough, and providing plenty of toys in the cage will keep bunny occupied when you’re not around. You’ll also get a handle on bunny ownership and have a better idea of whether you’ll be able to handle the bonding process
