Is anyone having problems with their birds having what seems to be a "cold"...sneezing and weezing? No nasal discharge or eye crusting, just really congested in a few hens and mouth breathing. I am so afraid i may have to cull if this is something really bad and that would devastate me because I finally have the breeds I want and had to really work at finding some of them. I have been treating with the Oxcycicline (sp?) and vet rx, giving yogurt and extra breads and greens. They have an appetite, but seem to be having trouble breathing and sound congested in the chest when I hold them up to my ear.
