Little colds that do not kill?

[GingerJane]

Hey! Does anyone know a small cold that last in chickens for a while and doesn't kill them? And what are the symptoms? Just like

when humans get sick and only last a while??

Chickens do not get colds. That is a common misconception. What they get is a respiratory infection and while some can kick it, others can't without the help of antibiotics, so will continue to sniffle and snuffle and sound congested until they are treated or die.
