Very fat adult Guinea Pig introduced to baby female Guinea Pig?

[Bobby Sacamano]

I just bought a female Guinea Pig from the pet store. She is very small, she cannot be more than 3 weeks old at the most. My male Guinea pig is over 2 years old and very fat (obese). The moment I introduced the female into the cage, my fat male Guinea pig started to make rumblings (I assumed he was horny), and it looked very obviously like he was trying to have intercourse with her.

Is my female too young to have sex and/or have babies? My Male is roughly about 5 times the size of her. Can they have intercourse despite the size difference? They are current;y separated until I garner the correct information

Thank you.
OK, judging from the "PETA" responses, I am going to bring the two together. I want babies, and by God darn, I am having Guinea babies! I want little buggers running around, it will enhance my life. Thanks!

well guinea pigs can breed in 60days from birth im guessing that the baby female is more than 60 days old so don't put them in the same cage together unless you want a lot of baby guinea pigs

She is far too young to have babies. It is possible, but if she were to get pregnent so young it would Kill her. Don't risk it!

Get you boar neutered, and 6 weeks after the op they can be introduced and should get along great.

Edit to Clarify, since the answer below seems to be confusing my response...

Guinea pigs can breeed from being 3 or 4 weeks old. so she is old enough biologically, However, she is FAR TOO YOUNG (as the other poster said, she is far too young to hae babies safely.)

If the strain they put on her growing body doesnt kill her, it's likely they will as they grow (they can rupture a young guinea pig's uterus).
