poor balance and lethargy
(Nth Qld, Australia)
We have a 10wk old Rainbow Lorikeet. He lives with our 5 year old indian ringneck. Over the last 2 days, the lorikeet, has developed very poor balance, ruffled feathers, and lethargy.
Our birds live in a large cage, Have access to fresh water, seed and wet feed. They are wormed regularly and there is no sign of mites. The Ringneck has no symptoms and seems to be quite healthy.
What illness could our lorikeet have?
