Yes i know he likes to culture and swab first. Baytril is a go to in my arsenal when i get a resp issue and it has worked like a charm over the years for me. As far as humidity goes. Humidity affects humans differently then snakes. Humidity for humans help in breaking up flem to be able to cough it up but it doesnt male the infection go away. A snake cant hack up the phlegm like we can. Higher heat and lower humidity along with medicatio. Will clear up a resp infection faster. You have to jump on it as soon as you notice an issue cause if it goes too far it can reach the point of no return pretty quickly.
