Sebastian does this thing every once in a while where hell squak like he's being hurt and hell raise his right wing at the same time and he wont let any one touch him for a while. when i first took him to the vet for that, she just said there was a blood feather that was hurtin him and sure enough-there it was! but lately hes been doing it alot lately and there is no blood feather at all! and the way hes doing it--holding his wing almost straight up, it looks like there may be something wrong with his joints. this may sound stupid, but does birdie arthritus exist? My vet still seems to think its just a troublesome blood feather....GRRRRRR! any input would be great. Thanks.
