problem guinea pig!

Question
Hi!
We have just adopted a young desexed male guinea pig from an animal shelter. We already have 3 adult females (all about 15months old) who all love each other and live happilly together in a large outdoor hutch and run. We were hoping that the new baby would join the 3 adults but we have had problems introducing him. At first all was ok, the girl pigs accepted him and he happilly followed them around. After a few days we noticed that one of the girls was not eating properly, the new male was constantly chasing her and she was terrified.After one particulary aggressive chase i picked her up to discover that he had drawn blood.  We kept her away from him and allowed him to have contact with the other two but he turned against one of them, biting and chasing aggressively. Which left one lady for him, who didn't seem to mind him following her everywhere and seemed to be able to put him is his place if he was getting too boistrous. Then we noticed he was starting to attack her too. This all happened in the space of 10 days. All three girls are now happily back together and seem to have forgotton about the boistrous baby but he is now living on his own inside and seems distraught. We have built him a new hutch and just need to make a few adjustments, then the plan is to put his new hutch outside so he will be able to see the girls and there will be a partition in the run so they will have the sense they are together without the possibility of him harming them. We don't know too much about his background only that he was siezed by an r.s.p.c.a inspector due to neglect. My questions are:
1.) Should we try to re-introduce him to the females once he has settled into his new home and if so, how do we go about it?
2.)Is this kind of behaviour typical?

Aside from all this bad behaviour he is a lovely, sweet gentle guinea pig and loves nothing more than lying in our arms and being fussed over. But he does get so upset when he hears the other piggies squeeking that we would love to find a way to get them all back together. I hope someone can help.

Hello,
it seems that they did have a bad introduction but all is not lost. It may take several tries and a lot of patience. Right now the idea that you have to put the cages side by side without them being harmed is a great idea and really suggested to help them get to know each other. The chasing and nipping is normal dominance behavior that's exhibited. When blood is drawn and they start truly attacking it's time to seperate them for a few days and try again. It is possible that he may be having a really difficult time and you did the right thing by taking him out once you saw blood is drawn. There are methods to try and help introducing guinea pigs.

Below is a link of suggestions on how to reintroduce them.
