So 2 days ago I purchased a new budgie, Lime, because I wanted my other budgie to have a friend for when I start work. Lime is currently in quarantine and during that time I was planning on training him. However, Lime lost one of his large tail feathers today so when I looked at him more closely, I noticed he has little pin feathers all over his head! I am just wondering if it would be bad to try to train him during a molt? Should I just leave him alone? I don't want to stress him out.
