Introducing piggies to a new one.. Trouble!

Have you read Guinea Pigs Social Life The introductions section is about halfway down. And it's VERY important that all the pigs be taken out of the cage, and that absolutely nothing in the cleaned cage smells anything like any pig that's going back in it. That means wiping down all the surfaces, including the wires, washing everything washable, and preferably rearranging the cage so that it's not familiar to any of the pigs. You can use soda pop boxes for hideys for a while until things settle down.

If no blood is being shed, you should let them alone to work out their problems. You're complicating things by separating them and then putting them back together again.

A 3x4 is the minimum size recommended for four pigs, so you're really crowding things somewhat by trying to put another one in at this point. If these suggestions don't work, I think I'd wait until after you build the larger cage to try to put them together.

Yeah since i am planning on expanding im hoping That will Help and I will clean everything and will introduce them in another spot and I read the social life i will keep all of that in mind when I expand and clean everything and introduce them. Thanks! lol
