Saphira and Snuggs, are you shooooo-er you're talking about yellow and white? Because I've always been taught that yellow goes with green and white goes with blue. According to my studies, it's impossible to end up with a white and yellow bird unless you have a genetic miracle (and even then...I'm not so sure). Are you misinterpreting the "white" as shades of yellow? I love budgie mutations, so can you tell me where the white is on her body? Sorry I'm a budgie fan

Btw, that's a beautiful color on a Cocker.
