chewy the cockatiel has a small raw wound on his wing elbow he fell out of the nest as a chick he is around 6 months old, boath his wing elbows are bald and when i tried to put a bird dipper on him the velcrow scraped his left elbow it seeped for a few seconds and stoped i followed some advice from my avian vet to put some polysporin on it yesterday and today. but he has started hissing at me and won't come out of the cage on his own.

hes eating and drinking normal i was told to not let him fly for 1-2 weeks so that his small flesh wound won't bleed again. i was woundering if it realy takes 2 weeks to totaly heal from a small velcrow scrape? and if there is anything else i should do?

i got him 3 weeks ago and he was un tamed and he had just started to come out on my finger and sit on my shoulder! i want him to like me he still talks to me and whistels but he is scared to death of me! what can i do? and i just notticed this wierd spot on the wing i'm sending pics. thank you, andrew ferguson.
