3 piggies.

Question
Well first off I just want to say it's wonderful that you take time out of your day to answer questions so thanks you.

I guess I should explain my situation fully. I bought a single female pig in november named surrey she was wonderful but she quickly became super aggressive and constantly teeth chatters and absolutely hates it when you touch anything in her cage. Our vet just kind of passed it off as cage aggression and we dealt with it. Then in January we got our 2nd female named Scarlett we had to quarantine her longer than recommended because she had a uri and she was the sweetest thing always wanted to be held and she was even comfortable to close her eyes and sleep when we had her out but now that she's a bit older it's like she wants nothing to do with is anymore and runs when we try to get her out and has even started teeth chattering she hasnt however bitten us unlike our first that draws blood. Now is where it gets complicated after she was better we decided to socialize the two we had in a mutual territory like the vet told us and to put it lightly they hated each other on sight and we have tried countless times o socialize them and it just keeps getting worse surrey our eldest bites scarlett and at first Scarlett was okay with surrey being the dominant female but now she's fighting back so we kept them on separate cages I thought maybe getting a third would help but Remy was sick as well with ringworm
And we couldnt socialize her but I have no idea if she's better cause she shivers constantly and that makes me think she isn't I've put them together on the bed to socailize anyways and it hasn't made a difference the two older ones do nothing but fight and the baby hides. I just bought a very big c&c cage cause I couldn't deal with 3 separate cages but I'm starting to think it may have been a bad idea and im nervous to have them
In there all together by themselves. I just can't make them bond. Any tips would be appreciated.

Answer
oye tough crowd.

okay well cage aggression is often linked to too small a living space, and agression between guinea pigs is usually caused by the same thing, if you look up c and c cages that will give you an idea of the right size (if you havnt already) have a go at building one of those, they are cheap and awesome and then you'll have the right amount if space.

if you already have sufficent space then ignore that, you just need to start working on bonding methods.

firstly have their cages side by side so close that they can poke their noses through and bite each other, then every day swap them over, also once a week take them out for a drive in a cardboard box together, they become scared and think of the other as comfort, while your doing that someone else needs to clean out one of the cages with a watered down disinfectant wich both will then be placed in. another good thing to do fortnightly is a bath with a rodent shampoo and while they are in the bath scared someone else cleans out their hutch. from here it is just a matter of rinse and repeat until they get along fine in a cage. but remember if it is too small then they will never get along. if however the size enough and they are still fighting then as a last ditch effort i would recommend and neutered boar, they have a habit of keeping the peace.
