I just got a new female guinea pig Monday night. I have 2 already, and I know that she was quarantined before i got her. She is aroung 4 to 5 months old. My question is when should i introduce the three. The other two are 11 months and seven months and quite a bit bigger. I am worried about my new little girl because all she has done the past few days is hide in the corner and has bearly eaten and hasnt drank anything at all. Should I wait to introduce them or would it help her? I don't want her to be alone to long if she doesn't have to be. Any help would be appreciated.
