introducing a baby guinea pig to my 2 adult female guinea pi

  i currently have 2 girls which are both 1 year old, im thinking of buying a 3rd pigs (a baby one) but i was just wondering if they would all be able to live together in the same hutch? or isnt this possible to introduce a baby to 2 adults? please help thanks

(I want another female)
Yes Absolutley. Now The Baby HAS To Be A Female So It Won't Mate With One Of The Adult Females. 3 Females Is A Great Way For Them Not To Ever Get Bored Or Lonley I Actually Would Reccemend This To Anyone Who Has A Guinea Pig:)
Guinea Pigs are really nice animals and rarely fight, if they do only a Little and soon get over it. And usually Males tend to do the bickering more than females do. If they do try and fight with him then it will only last several minutes, let them work it out, they will get used to each other quickly and become friends. Most likely though they will not fight and they can live together happily.
NOOO Dont do this They will fight. And they will mate. I have had guinea pigs die!!
