timneh gray

We have a timneh gray that suddenly started flapping to the ground everytime we try to take him out of the cage ,or picking him up from the play perch. I dont know why he reacts this way, i will take him out of the cages then he flaps to the ground uselly injuring himself so that he bleeds and then i take him to my shoulder and he will be fine from there exept if i put him on his paly perch or cage he will then try to flap away again.

This really just started suddenly i can't find a reason for this, can anyone help me find the cause for his behaviour, stuff i have to look for as i'm out of ideas to get my loving timneh back?
