I forgot to ask, what would be a good partner for her? I'll be getting her a friend in the future (maybe a year later). If I want only wf pearl or wf pied babies, what mutation shd her partner have?

 

Its impossible to tell male/female in pearl cockatiels visually. Sometimes the parents' mutations can help but not always.
As for partner:
If the bird is a male, then you cannot avoid getting female pearl chicks. To get as many whiteface/whiteface pied chicks as possible then a whiteface or whiteface pied female would be the best partner.
If the bird is a female, then if you pair her with a whiteface/whiteface pied then you will only get whiteface/whiteface pied chicks.
Hope this helps 😊

 

Thank you!! I have a gut feeling she's a female tho. She's really quiet and doesn't interact with the other birds unfortunately.
She's still very aggressive towards anyone who approaches her 🥲 hope she quickly adjusts to her new home

 

Also, would I still get the same results if I paired her with a pied cockatiel split to wf and pearl?
