My cockatiel has a growth on his wing
Side view of growth on bird
Wilbur, my 18 year old cockatiel, randomly fell off his perch back in December and bent a feather out of place on his left wing.
There was no blood, he expressed no discomfort, and he didn't fall again, so I thought nothing of it.
However, now in that same spot, he has a rather large growth. I don't think it's a blood blister, as you can see his skin, but I haven't ruled it out. I was away at school for months, and my parents didn't tell me about it. They told me it grew bigger this past month. It's pretty circular, and the diameter is about an inch. He doesn't seem to be in any pain (he acts like it's not even there), and he still moves the wing and stretches it out and cleans it, but I am worried.
I want to take him to the vet, but he get anxious and scared very easily, and I don't want the trip alone to make him worse. I think I might might a vet who does house calls, but before I book an appointment, I just want to know how serious to his health the growth might be, or what it could be.
If it's really bad, I want to take him asap, but I don't want him to go through unnecessary stress if it's not urgent and he can wait for the house call.
