Hi LCBL, and welcome to BB! Getting into a whirlwind about rabbits is quite natural, because they are so. darn. cute.
You need to separate all the rabbits from each other. Read below to see why.
You’ll need to take a step back and do more research about rabbit bonding (https://binkybunny.com/BUNNYINFO/tabid/53/CategoryID/9/PID/940/Default.aspx), and from there, assess your situation and what you think is the best course of action to implement immediately.. Important items to keep in mind:
1) All your rabbits seem very young. Sexing rabbits is very difficult; professionals, breeders, owners, etc. can get somewhat of an idea based on what it looks like down there, but on a young rabbit, nothing has really developed, so it’s an educated guess. Because of this, having 3 young rabbits together is very dangerous because one, two, or all three could be males, and pregnancy occurs in literal seconds with rabbit mating. I’m unsure the age when pregnancy can occur, but you must separate all three rabbits from each other. The likelihood of a mis-sexed rabbit is quite high, and you do not want a surprise litter or litters on your hands.
2) Especially (required) for male-female bonds, all parties in a potential bonding scenario need to be fixed (spayed/neutered) first before putting them together is all right. This is important for a number of reasons. Without being fixed, the rabbits will have hormones coursing through them, driving them towards territorial aggression and mating frustrations. This causes rabbits to fight to the death, breed whenever possible, and get into tussles. Currently, all your rabbits are young, so they may be getting along because their hormones have not activated yet, but within the next month, or even tomorrow, the hormones may kick in and you may find a fight broke out, or a humping episode has occurred, in which case pregnancy may be in the midst. Bonding aside, spaying females is extremely important due to the high risk of cancer associated with un-spayed females. Both spays/neuters cannot be done until your rabbits are ready. For males, it is when testicles descend (anywhere from 3months to 8months) and for females, I believe it’s generally 5-6months is the minimum so the rabbit is strong enough for the procedure. Until all rabbits are fixed, and after waiting a month after the fixing procedures so the hormones regulate to normal, the rabbits need to be separated.
3) Due to the information above, you’ll need to dedicate a good amount of space for each rabbit. I suggest a cage and x-pen for each. If this is something you cannot accommodate at this time, considerations for re-homing one or two the rabbits may be wise. At times like these, sometimes such a decision is necessary for the betterment of all animals/owners involved.
It’s wonderful that you’ve opened your heart to these rabbits, and worrying about breaking bonds is very thoughtful. To ensure the longevity of both happiness and survival for all these rabbits, think about what you’re able to provide, and if it falls short of what 3-rabbits require, there’s nothing wrong with responsibly letting one or two go to rehoming associations and rabbit rescues. Your anxiety and worries are natural, so reading and educating yourself can help you fele a bit more stable and figure out how to make all the rabbits happiest.
