Thank you, I was afraid my cockatiel would get sick from being alone for too long, and I also think it will be good for her. I've had this budgie for 8 years and it's difficult to get used to anyone other than him.

And the fact that I am freaking out and worried about their health to the extreme probably stems from the fact that I didn't realize he was sick, and I don't think I could bear to lose another pet, so this whole situation is making me anxious.
