We purchased 3 male infant guinea pigs in November (they were together in the shop) and they've been living together relatively happily, until the last couple of weeks. Their names are Ginger, Bowser and Squiggles (kids chose them!)

There had been a little bit of "bullying" between Ginger and Bowser. Bowser was the smallest of the 3 and Ginger would chase him away from the area where he and Squiggles were. It seemed to be a bit of 3's a crowd.

Then a couple of weeks ago, we can only assume Bowser reached his limit, and he attacked Ginger, causing injury. We separated them, but did reintroduce them - perhaps a bit too fast in hindsight after having read more online, and again, they've had another fight where Bowser has injured Ginger. So now we have Bowser and Squiggles living together and Ginger is on his own (and a shadow of his former self which is really sad to see).

Now I don't know what to do. I've come to the conclusion that we need to keep them permanently separated, and so I need to look at getting another piggie to keep Ginger company - considering the other 2 seem to get on fine at the moment, but I don't know whether it's better to try another male of a similar age, or a younger/older one, or should I get a female instead and look to get Ginger neutered?

Me and my husband both had guinea pigs growing up and never encountered fighting between them, and so we never really considered this to be an issue as they're well known to be sociable creatures.

I now know the pet shop we purchased them from shouldn't have sold us 3 bores based on research I've done since, and so I don't really know where else to turn to. Any advice would be greatly appreciated. Thank you
 
I’m sorry to hear this.

They should not have sold you three boars, it almost always ends in failure and the cage sizes required to attempt it will also be considerably more than they likely told you - to anyone brave enough to attempt three boars, they need an enclosure of at least 3 metres by 1 metre but even that won’t resolve the compatibility issues they face.

You do need to separate them permanently. Keep bowser and squiggles together. They require a 180x60cm (6ft) cage.
Ginger will need to be kept side by side with them for interaction between the bars only.

Ginger will need a new friend but you should not neuter him and get him a female if all your piggies are to continue living in the same room. A sow should not be introduced into the room where a boar pair lives as even smelling a girl may make squiggles and bowser then fight.
The only way ginger can have a girlfriend is if the two of them can live in a different room to bowser and squiggles.
A Younger boar can work best because a baby is less likely to challenge for dominance while he is still young. But that isn’t a guarantee that remains once he also gets to his teens.

The best thing is to contact a rescue centre and ask for their help in finding a compatible friend for Ginger. They will ensure they get on before you commit to the new piggy.
If you were to buy another piggy from a pet shop then as an on spec bonding does not allow you to test them for compatibility first, if they do not get on, you will be left in a situation of them both still needing to be kept in separate cages.

Bonding is a specific process which has to be carried out on neutral territory. I’ve added a guide below to explain the process, but you cannot just put a new piggy directly into Ginger’s cage as it will cause a fight.
