I bought 2 baby male guinea pigs 2 weeks ago and I'm wondering if it would be OK to get a young female rabbit... would theyy get on OK?

It's really not a good idea. Some piggys and bunnies get along okay, but it's hit and miss, mostly miss.

Also 2 males against a female, not fair.

Piggy's and rabbits have different needs, both in environment, food, and care.

Stick with the two piggy's. :)

I would suggest keeping them in separate cages.
What breed is the rabbit?

That's a good suggestion. If they're in separate cages, but side by side, they can still socialize, but the issue of fighting won't be as great.

Breed of rabbit doesn't really matter. Rabbits and guinea pigs can get along, in fact we always had a rabbit and piggy together when I was younger (but ours were the exception, not the rule). It's the fact that there are two guinea's, both male, and only one rabbit that is a major concern.

Rabbits are wonderful pets, but, unaltered (spayed or neutered) they will become aggressive at around 6 months of age. Guinea pigs are the same. It's simply not a good idea to put two against one.

Again, I'd stick with just piggy's, unless you're willing to get a separate cage and adopt a bunny. The humane society is a great place to find either animal, piggy or rabbit. Most rabbits are altered before they're adopted out, and there are also many bonded pairs that can be adopted together.

Just a thought. :)

When I had my rabbit and guinea pig they had "playdates" together. They pretty much ignored each other and went about there business. I wouldn't cage them together, a rabbits kick can easily kill a guinea pig, even if their just playing together. Plues, guinea pigs are herd animals and would do better with more of there kind (I'm not sure of rabbits)..

Rabbits are herd animals too. They live in groups their entire lives in the wild. They don't like to be alone, but it's recommended to get them another bunny friend, not a piggy. :)
