Swollen eyes, What is wrong?

[GreenFarmers]

A couple of my girls have recently developed severely swollen looking eyes, some are lethargic and many have a runny light brown poop. I adopted what turned out to be Battery Chickens.

Since they have come production out of my previous 10 has dropped until now none of my Chickens in the same coop are laying, and 3 have died. I treated for worms and am not sure what to do now. Are all these symptoms related?

Does the head have a horrible odor?

 

[GreenFarmers]

No. It is damp in the picture because I sprayed some wound care spray on on her eye.

THen it isn't likely to be coryza. THat is the only one I am familiar with.

When they are sick or in a molt, they will stop laying. If they are battery hens, they are probably getting ready to molt. Hugely swollen eyes can be from several carrier diseases such as MG, Coryza, and others if they are complicated with a secondary infecton. They could have been exposed by the person selling them or where they were kept. Many people would cull the sick birds, but if treating with antibiotics, they can still be carriers. Here is a good link to read about the above diseases and more: http://edis.ifas.ufl.edu/ps044

A course of antibiotics it's the only course of treatment. Erythromycin if you can get should alleviate their symptoms but as Eggcessive has said they will remain carriers. Times of stress may bring the symptoms on again and affected birds usually experience a decline in egg production.

Here's a source for purchasing antibiotics.

And this is a nasal flush that can speed the recovery of the eye swelling.
