Guinea Pig Stressed And Horny

[VeganIzzy]

So I got two Guinea Pigs yesterday, they are sisters. I handled one today, Parsnip, and she was happy to be out of the cage, however upon Parsnip leaving, Raisin began running around and biting on the cage, so I put Parsnip back in.
I am worried however as Raisin has been what seems to be harassing Parsnip and making a noise, which after watching videos I have identified as a noise they make when horny. She also mounts Parsnip, causing her to run away and squeak. Is there a way I can prevent this? Is this down to stress? Raisin will also run away from me, but Parsnip seems to be great with being handled.
They're both 10 weeks old. Thank you.

Hi and welcome

Guinea pigs always need to establish a group with a working hierarchy in any new territory and composition. Sometimes, it can coincide with a season, so it is that bit wilder as the first few seasons tend to be stronger. You have to sit it out. It is an absolutely vital part of their bonding process and social behaviour.

Please take your time to read through these behaviour guides to understand what it going on.

Completely agree with Wiebke above. Some of our girls seasons have been mayhem! They do calm down in 48hrs or so often even a day. We have Large wooden sticks as houses in the girls cage

This means the piggy been harassed always has an escape route
