Just wanted to give a heads up that my Ameraucana, Reba, just passed away and I had a necropsy done which came back with "Acute necrotizing tracheitis due to infectious laryngo-tracheitis virus infection"(ILT). ILT is caused by a chicken herpesvirus and often produces necrosis, hemorrhage and viral inclusions in the tracheal mucosa. It is HIGHLY CONTAGIOUS from bird to bird and is usually spread by aerosol droplet. Domestic Chickens, pheasants and peafowl are susceptible. The incubation period is 6-15 days. Recovered chronically infected carriers of the ILT virus can shed the virus intermittently, thereby infecting naive birds.
I just wanted to point this out because the Vet that I dealt with said that is this the second reported case of this in PORTLAND, OR this year! Most of us don't do a necropsy (which is how this is diagnosed, there is no test to diagnose while the bird is still alive). This could be alarming with the number of people who have backyard flocks now, especially with spring coming and everyone wanting to add to their flock with the new babies!
Please read about it before adding new members to your flock and keep a close eye on your current flock. Chickens that have this will have swollen, watery eyes (conjunctivitis), shake their head a lot due to mucous in their nose and airway, they will cough and sneeze frequently and they may open mouth breathe. My hen, would cough when she would eat and open mouth breathe when you would pick her up but no other symptoms. She was a carrier of this for many years and then it overwhelmed her one day and the end result was the hemorrhagic trachea.
Thanks to everyone taking note. Keep an eye on your girls and if they start to show any signs, isolate, call the Vet and bleach your coop.
