I would like to thanks this post and share my experience to avoid future trauma.
We had a tamed budgie 9 months ago, magnetic to all family members and do not like spend 1 min in the cage except eating and sleeping.
Kids like to play with them and the budgie like to involve and he may think he is human as well I believe.
This morning 8:55 am my daughter accidentally step on him and reported to me immediately. When I saw him, he still alive and walking on the ground. could not fly. I hold him and called avian doctor to the 9:45 am appointment right away. He closed his eye and seems sleeping, and open his eye sometimes, trying to move the wings, not good feeling for me.
Arrived the clinic 9:30 am and doctor did the assessment and give him injection and put into warm incubator immediately. Unfortunately passed away on 11:30 am for internal bleeding and spine injury
Very sad and hope other budgie owners aware the danger
