Chickens and the sick (MG, coryza, or who knows???)

[Frugalhomestead]

Someone asked if the sick ones had a bad odor from the face? That can be common with coryza. You have learned the hard way now about adding new birds to your flock that have been elsewhere. If possible, I would get a culled or dead chicken necropsied by the state vet to find out what disease(s) you are now dealing with. Coryza shows up rather quickly after a chicken is exposed, usually within 2-3 days. MG can show up a bit later. If birds are housed next to each other at a poultry sale or swap meet, they can be healthy and then be exposed to a disease carrier in the cage next to them. People handling birds can also spread diseases. If I had coryza in my flock, I would cull them. MG is more common in backyard flocks. I might treat or cull sick birds. Either way, consider all birds in the flock exposed and carriers for life. Sorry that you are dealing with this.

also no smell.
