My daughter’s cockatiel died a week after being moved from her bedroom to the basement. It’s an improved basement, but the air is damp and musty down there, especially compared to her room on the second floor of the house. Could that have killed the bird?
Yes it could’ve been. Cockatiel lungs are very sensitive. Mine unfortunately died because I used cooking spray. That’s how sensitive they are. Sorry about the loss. The bird needed to stay somewhere where the air is fresh and clean.
