Parakeet with large hump/lump on neck
(Forked River, NJ USA)
Yesterday it wasn't there but we noticed she was sleeping with her head down rather than back like usual. This morning, she has a large hump under her feathers on the back of her neck. Looks like she either has a fur collar or she's from Notre Dame. She's roughly 5 years old - parakeet. Nothing else about her is different - eats/drinks/etc. exactly the same but over the last 3-4 days she is a big cranky with her fellow buddies (3 other keets).
THANKS FOR YOUR HELP! Diane
