Since this is a house rabbit pet forum which encourages rescue and discourages breeding (and the topic of intentional breeding is prohibited), I have omitted some content from your topic for its approval.

Please see here for tips on litter training: https://binkybunny.com/infocategory/litterbox-training/
Note that litterbox training intact (i.e., not spayed/neutered) rabbits can be a losing battle, as their hormones are incompatible with what we conceptualize as “litter trained” most of the time. Also, realistic litterbox adherence expectations mainly center on peeing in the box — pooping is common outside of litterboxes due to rabbits’ nature.

Also, be aware that if they are being kept together and of the opposite sex, they must be separated immediately to prevent pregnancy. If breeding is your intention, this is not an appropriate forum for you. Additionally, they likely have what is called a “baby bond”, which is a bond which seems very secure and stable, but in actuality may dissolve very soon once one of them begin acting hormonally. For these reasons, separation now is recommended until both are spayed/neutered, 1mo post-recovery, and then you can begin the recommended rabbit bonding process: https://binkybunny.com/infocategory/bonding/

Their litter habits will be greatly improved upon 1) Hope getting spayed and 2) once they are both properly bonded. As of now, you likely have two rabbits territorially marking in response to each other/hormones (the presence of a rabbit not formally bonded to another/an intact rabbit can facilitate hormonal behaviors in an already fixed rabbit).

I agree with Wick that spaying will help a ton with litter training.

Do keep a close eye on them (look for fur clumps pulled or other evidence of fighting) to make sure they don’t start fighting as Patches starts to mature more. Pre-puberty rabbits will often get along, but then hormone changes will trigger fighting. If they do fight seriously, it can make it a lot harder to bond them, so many people recommend separating until spaying, especially if you can’t get them spayed right at 4 months. There are also some hormonal changes for a few weeks after spaying that can cause issues.

In terms of enrichment in their pens, can you give them some temporary access to a larger  bunny proofed area for part of the day to get extra exercise? Perhaps a tall puppy x-pen hooked up to their main pen?

Other “boredom buster’ toy ideas are toilet paper tubes stuffed with hay, willow twigs, phone books for shredding, paper or grass mats, cardboard box hides for “redecorating”, and organic palm plates. 🙂

The nipping and chasing is a sign that things are starting to get tense between them. Personally, I would separate them and keep them side by side. Currently they have a “baby bond”, which could very likely break once Patches’ hormones fully kick in. The only thing you can really do to help their bond is get them both spayed. The chances of an easier re-bonding are higher if you separate before a bad fight occurs. Things can really turn bad in a flash, and if you aren’t there supervising all the time they could get seriously injured.

This might sound overly cautious, but we have so many people come on the forum asking for help because their rabbits that had been together since they were young suddenly started fighting.

Gotcha. Yeah, if they are spending most of the day alone then I would definitely recommend separating them. I know it’s a huge pain, but I know of more than a few members whose buns fought so badly they weren’t able to rebond them later. 🙁

I can’t really say or predict that. I would hate to say “sure why not”, and then have them fight on Christmas Eve.

You are playing with “fire” by allowing them to interact when they are not bonded — they could get territorial/possessive over the presents and a potentially “cute” event could turn into a fight with injuries. It would be safer to split the presents and present them to each separately.

Since Patches is still very young, and both are unspayed, whatever bond they have is known as a “baby bond”, rather than a true bond, and can be very unstable. Adult rabbits tend to get a long with babies (pre-puberty), as they don’t see them as a threat. The chasing and nipping you are seeing is a sign that it is becoming even less stable.

Again it’s your decision, we can only advise on what we would do in your situation.

Regarding the Christmas thing, for my unbonded pair they groom each other and cuddle but at the end of the day they aren’t bonded so I have given them a stocking each and wrapped presents each and will just have them open them separately.

I don’t think your bunnies will like their presents any more because they’ve opened them together. Opening presents together can be a special thing for us humans but I don’t think our bunnies feel the same way. I think it can be just as exciting for them to open them individually with you 🙂
