Bourke missing secondary feathers?

[Star428]

He cant fly properly... keeps hitting things
Bourkes do shed feathers a lot but not in a chunk like this... don't see any stress bars or signs of plucking... its just here

Hmmmm, did he get scared by something? When birds get scared, they shed feathers. Maybe he is going thru a rough wing feather molt?!
