She's a lutino budgie. It's not the first time I've seen birds get sick like this, and she's still very active and does try to eat. But I can't help but be worried about it, since it's the first time she's ever been sick, and she's the only bird I have left.
That's a very cute bird. It's a good thing she still has energy and tries to eat. It's completely natural to be worried. Spending time with her should be a priotiry. I wish the best for her.
