What is going on with the Belled Bird's Tail Mao?

The Balli Bird's Tail was fell because it was changed because of changing feathers.This bird's feather change period is generally from March-June, and it will last about 3 months.Don't change food easily during this period. It is best to wait for it to fade the hair. When you start to grow new feathers, add some oily feed.At the same time, pay attention to cleaning, be clean and tidy in the cage, and clean up the falling hair in time.If you want to take a bath, don't be too frequent.
