Diet Switching Pellets Cold Turkey + Veggie Issues

[Rsr216]

Hello all,

About a week ago I adopted a two year old guinea pig from my friend who was no longer able to take care of her. She is unsocialized and is a lone piggy who rarely had play time outside the cage (she is slowly warming up to me though), but I'm planning on getting her a friend asap. I'm trying to get her to switch from Gourmet Recipe guinea pig food to Oxbow pellets. I'm wondering if I should just switch her food cold turkey. I also can't get her to eat her veggies. I've only gotten her to take a few bites of a carrot once and haven't gotten her to eat it since. I tried cutting it into tiny pieces and mixing it with her food but haven't had any luck yet.
Many advice would be welcome.

Thanks for taking her in. Here's some recommended reading for new pig owners:
