Lovebird Chick-- Lump on head

by Valerie
(Orlando, FL, USA)

Today I found a "surprise" masked/Fischer's lovebird chick. S/he is probably about 5 weeks old. What caught my attention is a swelling on the side of its head. I thought maybe an insect bite. When I caught her, there was no play in the lump, I tried shifting it to see if it was a skin issue or abscess. It seems solid, and starts under her ear.

I have every intention of taking her to an avian specialist, but wonder if I could have a few suggestions of what to expect them to find. I have had lovebirds since 2000, and never had a deformed chick.

Also, the chick had staining around its nares which indicates to me a respiratory issue, and the eye on the side with the lump (left side) has a slight puffy appearance.

Thanks!
