Coco (female budgie) has been sitting idle like she is exhausted for 5-6 days now. And when I keep her cage outside, she becomes active suddenly unless its raining outside... Has she got cold? She also becomes puffy when I keep her inside. I, nowadays have made it my practice to keep the cage covered but she still is not okay... Pls help me. Oscar (male budgie) looks perfectly fine. He just takes some frequent naps, but he used to take it from the day I bought so no problem. And also Oscar and Coco have started moulting. Coco got her brown cere and Oscar got his blue cere but that's an old news because it has been like this for over a month now.
