Oh my with what you have been threw you should have posted a list for sure ksKingbee
Sorry i don't have any any meds to add but i got some in my cabinet just in case if that counts as a choice
Tetracycline and Oxytetracycline are probably good ones to use if you can't get something like Baytril.
This shows the bacteria that @KsKingBee was dealing with a few months ago and they drugs that would treat them.
Ok see your info/ experience needs to be on this page also cause it is very important and mabe once this thread gets more good info it can be added or made a sticky for easier access later on if it gets buriedThe list of what worked for me is pretty short. When I was having my worst problem last spring it turned out to be a secondary infection caused by improper worming. I did the three ml per gallon as was frequently recommended and that did not work. The worms flourished and the birds got sick, and started showing respiratory problems. At first the vet wanted to save the 'Big Gun' Baytril for when everything else did not work so we ramped up until we found the real problem causing it all.
In the end when the worming was done properly the birds responded and are in general good health. My interest here is when not trying to treat a severe problem, what works for you? and how do you use it?
