Thanks for alerting us to this dreadful scourge. I have found an article that seems pretty good... Megabacteria - Articles and Links - it also has links on the side for further research.

That's heart-wrenching...sooooo soooo sorry to hear. Many prayers coming your way. I hope that your remaining flock stays strong and healthy!

wow, I'm soooo sorry for your loss.

So sorry for your loss. Budgies are, unfortunately, very prone to megabacteria.

The first symptom of megabacteria (which is a fungal infection and not bacterial at all) is weight loss. If a bird starts losing weight and does not have any other obvious symptom for it, the best thing is to put him on an antifungal. Megabacteria comes, mostly, from unsanitary situations: dirty cages, cages without a bottom grid where birds forage among their own poop, bedding not changed regularly, bowls made of plastic instead of steel, that kind of thing. It's contagious in that it can spread through feces (that's why the bottom grid is so important).
