How weird, I just started a "medicine kit" for the chickens. We have one for the horses, but they are such robust creatures. Chicken are not so robust.
I have VetRX.
I also have oxytetracycline (tetracycline) from the feed store. Terramycin = (oxytetracycline)
Sulfadimethoxine (coccidial infections)
Sulmet = Sulfamethazine sodium (coccidial infections and Coryza)
Aureomycin = Chlortetracycline: A TETRACYCLINE with a 7-chloro substitution for fowl cholera(Pasteurella multocida), Infectious Synovitis (Mycoplasma synoviae), Chronic Respiratory Disease (Air-sac infection), Mycoplasma gallisepticum and E-Coli. Infectious Coryza, Coccidiosis, Acute Fowl Cholera, Pullorum (egg-transmitted disease of poultry caused by the bacteria Salmonella pullorum).
Tylan = Tylosin. An antibiotic in the macrolide class. Other members of this class of antibiotics include erythromycin, clarithromycin, azithromycin, spiramycin, and dirithromycin. (Chronic Respiratory Disease caused by Mycoplasma gallisepticum).
I would use "Sulmet" and
Aureomycin before I used Tylan, but I have heard that Tylan works when Sulmet wont. You can get Tylosin at the feed store, it is expensive.
I use Lincomycin sparingly as it is expensive. An antibiotic derived from cultures of the bacterium Streptomyces lincolnensis, used in the treatment of certain penicillin-resistant infections
From what I can gather; Sulfadimeth
oxine, Sulfamethazine sodium, oxytetracycline, aureomycin and Lincomycin are really all we chicken lovers have to fight secondary infections. The viral infections have to run the course and hopefully the flock will recover.
I have disposable gloves, cotton balls, syringes, rubbing alcohol, peroxide and wonder dust.
The wonder dust is a horsey medicine for wounds, it really is a great product.
I also plan on obtianing sterile petre dishes with media for culturing these dieseases I can not diagnose.
I ran across a nice website that may help.

It has tables of symptoms and a possible diagnosis.
The internet and this forum are probably the best medicine for the flock !!!
