open that up down to the lowest dip in the air cell.... do you have bacitrim ointment or triple antibotic ointment WITHOUT pain relief?
his beak is more than likely located at the LOWEST DIP IN THAT AIR CELL so take shell off as far as you can go down to the inner membranes, take the ointment and gently rub it all over that membrane and then feel with your finger for his beak or even his round big eyeball...... then get his beak free he is shrink wrapped, try to avoid as many major vessles as you can by pushing the aside make just enough of a hole at his beak to get his nostrile free.
