Eyes/Non-crusty One brown and one pink ear?

It's probably just how her coloring is. My piggy has half white face and that ear has a random black patch on it. I call it her cows ear lol

Yes, it's normal. It's just depending on what the skin under the fur is like. My pig Gus had a half white, half black face and his ears were the same color of that side of the face. Nail color is the same way. Some have dark, some have light, some have a mix of each.

Guinea pigs cannot be albino. They are simply referred to as Pink-Eyed White's, or PEWs. The different colored ears is completely normal. My gray and white female has a gray ear on her gray side and a white ear on her white side. Also, my brown and white female is the same way.

PEWS as I know them are completely white with pink, red or ruby eyes with no other coloring at all.

There is no such thing as an albino guinea pig as SFailed said.

I noticed your photo in your other thread. Poptart looks like she has Himalayan in her. They are mostly white with brown ears with brown snouts and feet and red eyes They are solid white at birth and darken later. She might have just inherited some of the Himalayan markings. How old is she? I had a Himalayan and her markings would get lighter and darker. Someone said it was a seasonal change due to temperature fluctuation but she was indoors all the time so I'm not sure why the markings changed.

Mine has one brown ear and one white ear! We named him Nilla bean! For vanilla and a coco bean! lol nilla Bean
