Prior to being neutered and spayed, bunnies can’t really be bonded so really they need to be separated whilst their hormones disipate and then bonded properly.

Litter habits are probably rubbish right now for a couple of reasons:

-New environment so they want to mark
-Hormones spiking after surgeries which adds to the urge to mark.

Speaking of hormones spiking, it’s very common for bunnies of either sex to go through a hormone surge immediately after being spayed and neutered. So things such as spraying and being aggressive might get worse before they get better (but they will get better!) Litter habits should improve too but you should continue picking up poops and putting them in the litter tray to help get the message across.

Congrats on the new bunnies! If you’ve only had them for 4 days, its completely to be expected.

As Sarah said, their hormones are spiking following the neuter and spay, so it would be best to separate them. How were an unneutered male and an unspayed female living together anyway? They can’t have been bonded for long, or surely she would have been pregnant (not a criticism of you, I just can’t understand how).

If you keep them where they can see and smell each other but not touch, it should make it easier when you come to bond them together later.

Litter habits will improve with time. They’re in a brand new place and trying to establish their territory, so give them some leeway to start with. Peeing in the tray is the main thing, and many rabbits still leave the odd poop outside their litter tray, but pick them up and put them in the litter tray.
