Hi there, I could really do with some advice and support for my 3yr old boar Jett.

He was bonded with his father who unfortunately died 3 weeks ago. It was a very peaceful relationship and Dad was the boss. There were only ever a few occasions where dominance flared up but it would pass very quickly.

Jett was obviously grieving his Dad Tubby
We gave them time together after Tubby passed so Jett knows that he is gone. He became quiet and withdrawn and we knew we needed to find him a mate.

We took Jett to choose a new pal, which he appeared to do, a little 4 week old fluff ball. I'm in Australia living rurally so there were no rescues to try do longer introductions and bonding, so we have done the best we can to ensure Jett didn't decline from grief.

Over the next few days, it became obvious that he didn't want to interact with the baby, he wasn't taking him under the wing, he just sat in a hide very separate from the baby.

I also have another pair of boars in an adjoining cage that has a male slightly older than Jett called Possum, and a 5month old called Cream. Jett and Possum have always been curious about each other, screaming from cages to try get close.

We thought given that Jett wasn't interested in the baby, that we would give him a go with Possum. They already knew each other so they were introduced outside in a 5x4 grid run. There were usual dominance displays, but overall, it seemed to be going well and looked promising.

We moved them into a 3x4 grid inside on neutral ground, things ramped up a bit, but it didn't seem bad. Possum was laying in front of a hay bag and water bowl blocking access, but there were multiples in the cage, and a massive pile of hay to burrow and hide in, as well as eat. Possum seemed a bit incessant in his chasing and humping, but they would lay together in the corner, eat veg scattered around the cage, eat side by side from the hay bags, and it looked pretty good, with some wariness about potential bully behaviour.

The next step was to move into the proper cage in the lounge, the one Jett shared with his Dad. I extended it from a 2x4 with 2x2 loft to a 2x5 with the 2x2 loft and rearranged it so it was different. I also deep cleaned the cage and all bedding, using some of the bedding from the inside bonding cage. It's here I note there is only 1 ramp to the loft, I am awaiting 2 new ones. Otherwise there was 2 of everything, multiple feed locations, water etc. I started off with 3 hole hides, but had to remove them when it became obvious they were causing problems. I left hay (like LOADS) of hay to hide in.

Things appear to have not gone well. Jett has bite marks and scratches on his skin and after initially being more spirited and happy in the beginning stages of bonding, he became very withdrawn and quiet, and dropped a little weight. Unfortunately I was away over the weekend and didn't see if there was any aggressive behaviour to cause the injuries, but I have seen incessant chasing, blocking in corners, chasing off food, bailing Jett up in an increasing fashion so have dropped a divider in between to see what happens. Jett had a life in the corner and had to rumble and run any other place he wanted to go.

Jett has been moving around a lot more freely with the barrier in place. Possum is very unhappy about it, they are both rumbling at each other from other sides of the barrier, but overall, Jett doesn't seem as withdrawn and unhappy. He certainly isn't trying to break down the wall to get back with Possum.

Is this a bond gone wrong? Or is it an error on my part with the new cage not being big enough, or the single ramp? Yesterday when outside in the 4x5, Possum only left Jett alone when he was busy trying to mind the business of the other babies in the next door pen. When the babies were in hides, Possum went right back to keeping Jett in the corner. Now there is a divider outside too so Jett can actually move around.

My partner and I are still very much grieving Tubby so it's an emotional mess trying to figure out what is best to do. Any advice or suggestions? I don't want Jett to live alone on the other side of a divider from a bully.

I also feel sorry for Possum cuz he had a pal with Cream, I split them up, and now he is on the other side of a divider too. Possum was a solo pig rescue whose humans didn't want him so he didn't really know how to guinea pig anyway, but I want the best life for them all, but I don't want to add another 2 pigs in the mix either!

We have 2 4x5 outdoor runs, 1 3x4 inside neutral pen, and 2 2x5s with 2x2 lofts, so there really isn't any more space I can give! What do I do here?!
 
I’m sorry to hear this and sorry for your loss.

While it takes two weeks for a bond to be fully formed, what you are describing sounds like this isn’t a bonding which is going to work.
The fact Jett is happier away from Possum sounds quite clear that they should remain separated, I’m sorry to say.

The behaviours between the cages that you saw from jett and possum previously may not have been signs they would actually want to be together. It is very normal to see territorial behaviours between the bars - things like chewing the bars, laying together each side of the divider are not necessarily positive signs at all. They may well interact but territory marking doesn’t make it positive.

Your cage sizes nor the ramp are the issues here, this is a lack of character compatibility which you can’t change.

It does seem your long term solution is going to need to be to keep the two young ones (cream and the 4 week old) together if they are ok together, and that jett and possum need to live in separately.

Jett and possum will each need their own cage covering a minimum of a 2x3 cage side by side (you can’t split a 2x5 in half as it isn’t big enough).
You will see dominance and territory marking behaviours between the bars.

If it becomes too much and jett and possum can’t tolerate being side by side then you can see if you can find a way to reconfigure the cages so the babies are between them. That way jett and possum don’t need to see each other but the bonded babies become the neighbour to each single adult.

Is jett’s weight stabilised now?
How much weight did he lose?
 
It's so sad when they don't get on, you did what you thought was best though 💐

Thank you for being so thorough and considered in your response, it is greatly appreciated. I can extend one of the 2x5s to a maximum of a 2x6, and then they can have a small loft each too. If it becomes intolerable, I'll go back to the drawing board 🙌

Jett is quite a small fellow already, I suspect he may be a satin, unless it's just a very glossy black coat. He dropped 40g but I jumped in with some critical care on a spoon, bumped up the veg and gave extra grass time outside. He has stabilised now to his usual 870g.

I'm curious about Possum as he also dropped during this period, 1015g to 970g. Would it be possible he was so concerned with harassing Jett that he neglected his own eating? Or, could it be that he is unhappy not being with his original friend Cream?

I tried giving Possum and Cream some free range time together yesterday and the sparks well and truly flew. Cream is in full blown testosterone land and very much alpha pig. Possum has had a taste of that too now and was quite reactive. Before they were separated, Cream was constantly face humping Possum and he just let it all slide. They were good friends. I feel a bit guilty splitting that up because now Possum is such a different pig, it's not a nice personality that we've seen!

A huge part of me wants to swap the pairs, again, but I'm really messing around here and all the bonds could implode if I'm not careful! I also have to consider we have a 4 week old baby who is yet to show his pubescent colours too, I'm freaking out!
 
@Piggies&buns has given you great advice ! It’s always easy to be wiser afterwards - the baby really does need a companion to help him learn how a Guinea pig is etc
I’d put Cream with the baby and have Jet and Possum as neighbours - you are already seeing Jet and Possum putting weight back on. I hope you’ll have a lovely bond with Cream and baby 🥰 and two happy neighbours
 
It is possible that possum has dropped hay intake through the stresses of bonding.
Keep an eye on him.

You are right, all bonds could implode.
Cream and possum don’t sound great together.
I do think you’re only solution here is cream and and 4 week old together and jett and possum as neighbours

Thanks again for all the advice.

I just had Possum out to do a check over after he has dropped another 10g and see that both of his top teeth are broken off. He has been doing some serious cage biting of the c&c wires in the outdoor setup, since before the divider went in between himself and Jett. It would be the only way he could have lost teeth.

There is still a little of each tooth, so no open gum wound to clean. I've stepped in with Meloxicam and hand feeding with critical care. The exotics vet is 3hrs away and likely just finished for maternity leave, so I will closely monitor and take the drive if needed. There is often such little support in Australia, especially in rural areas.

Could it be possible that the aggression has been pain and hunger related? I mean, if you don't have teeth, can't eat, it would make sense to guard food and be aggressive, right? You're the boss of the pair and you can't consume your resources, that would cause a major personality change you'd think?

I can't say when the teeth broke. So I gueas it begs to ask, could it be worth one last try for him and Jett once he has healed a little, had pain relief, and can start to eat properly independently?

These guys.. Tubby's ashes and paw prints were delivered today, we lost him after a kidney stone removal, and now all Possum wants for Christmas in July is his 2 front teeth.. 😫😳🙏
 
Oh no! You are going through it emotionally, hopefully his teeth will quickly grow one of ours broke a tooth four days later it was back to full length! I was astounded 🙂
 
As he has lost 55g then that does warrant daily weight checks and preparing to step in with syringe feeding.

Any pain of course won’t help, so you could try bonding again but given you don’t know when the teeth broke, his behaviour may not have anything to do with it so do be prepared for it to not work and that it is down to a character clash.

I did think that, he was already starting to ramp up last week, and he can't have broken his teeth then. Otherwise, the weight loss would be much greater, even potentially starting to see stasis if he couldn't eat for that long.

I'll keep on the syringe feeding, pain relief, I weigh weekly and am also used to am and pm weigh ins with Tubby having been so sick. I'll also build a new cage so they are neighbours and see how that runs.

The other problem I'm going to have is stopping him from biting the grids and breaking his teeth again. If I put the corflute high and add nibble guards, he can't see other piggies. Is there any other option for panels so he gets the full sensory experience? Baby grid it maybe?
 
I've got perspex type sheets attached to my grids with bull dog clips to stop Red biting the bars after he broke a tooth.
I don't recommend baby bar grids, a friends piggy bit the bars so hard they collapsed, his top and bottom teeth were either side of 2 bars, he trapped his teeth and pulled them out trying to get away.
