Why are my young rabbits jumping and piling on each other? Is it normal?

This unfortunately happens sometimes where their bond is broken around the time they reach sexual maturity. It is wise to keep them seperated, because the mounting seems like aggressive behavior. However, I would have a vet double-check the sex of these two. I have seen many rabbits that were mistakenly identified as females, when they were actually males. This would also explain the mating behavior. You should also consider having them spayed/neutered at this age. I prefer to do this surgery around this age and it's quite safe when in an experienced surgeons hands. They will often cease the aggressive/mounting behavior after this procedure is done; and it saves from having a litter of unwanted bunnies...which is a big problem. I hope that helps and you can get this problem sorted soon.

Thanks for reaching out. Not all individuals get along, especially in confined areas. As young rabbits mature and hormone levels rise, territoriality and dominance are fought over to establish. Spaying the rabbits is necessary anyways, so now might be a good time. Keep separated for now. Good luck.

You need to separate the bucks (males). The adult sees the younger buck as a rival, especially in the presence of the does (females). It would be recommended to separate the bucks from each other and from the does. A doe can begin to breed as early as 6 months of age. Leave them together and you may find yourself overwhelmed with rabbits very quickly.

Mounting behavior is not unusual but I would recommend to have both rabbits checked out to be sure they are both males! You definitely don't want a bunch of baby rabbits! Male rabbits can sometimes become aggressive so neutering them is a good option to decrease aggression. You can discuss the surgery with the doctor during the visit to see if this is a good option for you.

Hi and thank you for your question, Most rabbits reach sexual maturity at the age of about 4 months, but this also depends on the breed, size and individual differences. Males may try to mount other rabbits and/or become territorial and aggressive. Females often become aggressive and may bite. In males the testicles become developed and descend into the scrotum on each side. Regards

This is part of dominance behavior, and the one humping the other is showing she is the top bunny. I wouldn't be concerned about it, but I would stop any aggression and separate them immediately. By the way, I love their names :-)

Unfortunately, it seems like they are not bonding well. This happens even amongst siblings. Desexing is a good thing to do, but should not be expected to help them get along. I wish I had a good remedy for this problem, but these are tricky scenarios and sometimes they have to be separated.
