Well if you don't get them fixed, bonding them will for sure result in babies. And breeding constantly all the time for the doe is not good. Does can breed again right after they have a litter of babies. Which means if you keep them together you would have baby bunnies every month. And that's hard to deal with if you do not want it.
if the bunnies are siblings, I recommend getting two females, so that they won't have babies, that DON'T breed with any other bunnies.. If they breed with someone else bunnies or you get a male one day, the two girls would fight each other.
Two males will fight.
If you really want a male and female, I would at least get one fixed. That way they can't have babies.
As for a cage setup, both ideas you have are great! there is pros and cons to both of course tho.
X-pens are great from what I've heard, but if you don't have a good enough cover, the bunnies will jump out.
C and C cages are pretty great as well, and I would love to have one one day! They can get expensive and do require some handy work though. For really good videos and ideas on those types of cages you should check out Stormy Rabbits on you tube. she has had many of those in the past and her ideas and way she built them is pretty cool. There is also plenty of good ideas for bunny cages on Pinterest! I remember when I was looking for an indoor cage for one of bunnies. I scrolled Pinterest and You Tube constantly :lol:
Bunnies make great pets and you will soon find out how fun they are! They have great personality, almost like a dog! They're unlike most small pets people have. Unlike guinea pigs, they're more active and wild!
It's so fun to watch them hopp about, and they will become your best friend.
