Probably not smart enough to be throwing my 2 cents worth in here but here goes ....

In a bird that is so sick I cant see any of the above working however I have used Rescue Remedy for myself , my kids and my animals for years when stressful situations have occurred .
The Raspberry Cordial is used by so many bird keepers and was also given to soldiers in the WWars to ward of impending stomach bugs .
Ive seen the relief a coffee enema can give to a person in serious pain due to a terminal cancer .
When Condys was available Ive used it to cure fin rot on fancy Bettas with excellent results .
Surely its worth keeping an open mind on such things . People wouldn't stick to these things for years if they didn't get positive results . With the right application and if the ailment isn't too far gone then these old time remedies often are effective.
I do not know of anyone using Col Silver however I have had it prescribed by a naturopath and probably would have tried it if it wasn't so expensive.
This is just my opinion
