1. Fowl Cholera
You should be suspicious of this disease if you see your birds begin to have a greenish or yellowish diarrhea, are having obvious joint pain, are struggling to breathe, and have a darkened head or wattle. Fowl Cholera is a bacterial disease that can be contracted from wild animals or food and water that has been contaminated by this bacteria.
So it is usually better to put them down and destroy their carcass so it will not be passed.
But there is a vaccine for your chickens to prevent the disease from ever taking hold.
2. Infectious Bronchitis
This disease hits close to home because it wiped out half of our flock when we were new to raising chickens. You’ll recognize this disease when you begin to hear your chickens sneezing, snoring, and coughing. And then the drainage will begin to secrete from their nose and eyes.
Their laying will cease too.
But the good news is you can get a vaccine to stop this disease from impacting your chickens.
However, if you decide against that then you will need to move quickly when seeing these signs. Infectious Bronchitis is a viral disease and will travel quickly through the air.
To treat Infectious Bronchitis, give your chickens a warm, dry place to recoup. I gave my birds a warm herb tea and fed them fresh herbs, which seemed to help.
