No I'm afraid not! These symptoms are merely a warning of things to come, when they start to
look properly ill then it's even harder to correct it.
Your going to need a vet and an antibiotic of some kind if it is an infection. My vet visit was £18 and a 2 week course of baytril was £6. Really didn't cost a lot!
There are things you can do to help but you'll need to do these
with the antibiotics. You can up temps slightly and night time temps too. Chams don't get fevers to fight infections so the extra heat may help him along.
You can also help clear the airways by using a warm mist humidifier or what I did, put him in the shower room with the shower running so he can breath the warm air.
Most importantly, you need to find out what could have caused the infection a d do your best to correct it. If its not corrected promptly then the cham isn't going to be able to get better.
