My budgie recently got attacked by a hawk, not very badly. the hawk only had enough time to grab his wing. The wing seems fine, and there was no blood. But all of a sudden he cant balance, on anything. he just falls off his perch, but there is no known sign of injuries on his foot/leg.
He also chews on everything he see's in a very aggresive manner, im very confused and dont know hes doing this? it only happened after the "attack".
Please Help?! im afraid he could have nerve or brain damage?
