We have an approximately 3 mo chicks we bought from a grower. The grower bought from Ideal Poultry as hatchlings.
A chick had thick clear drainage from the eyes. Slept all the time. Ate very well though. Took water from dropper sometimes.
My wife took her to the vet today who diagnosed her with Newcastle disease, but from what I read, it doesn't really exist in the USA unless what I read was dated. It was a clinical diagnosis, not a test - positive diagnosis.
The vet says to destroy our other pet chickens, but care for them so we don't want to do that. No symptoms in the other chickens.
How likely is a misdiagnosis? Are we doing wrong by not putting to sleep our other chickens?
I could really use some advice.
