All that white is a sign that she's dehydrated, so keep giving the fluids, and do *not* force-feed food until she is hydrated. FYI, I have a sick one now too that I just started treating. Below is my treatment plan, it's one that I've been using for years, and if the bird has a treatable disease, this works very well.
Done so far:
- Weighed - 2kg at 10 am
- Gave antibiotic, Corid, & Baycox
- Tubed 60 ml at 10 am
- Tubed 60 ml at 11:30 am
Later today
- Will tube another 60 ml at 1:30 pm
- Will tube 60 ml baby bird food at 3:30 pm
- Will tube 60 ml baby bird food 9:30 pm
Tomorrow
- Weigh
- Medicate
- Tube 60 ml baby bird food ever 4-6 hours
The above plan guarantees that the bird will not die from dehydration or starvation, and will buy the extra time needed for medications to start working.
