What causes milky white eye discharge in chickens and how to treat?

It could be a touch of conjunctivitis but usually swollen eyes are the first sign of Mycoplasma infection which also cause respiratory problems. They will always have Mycoplasma and stress will trigger it, but the first instance is usually the worst. Even if you don't have a vet who will see chickens you could ring them to get a dose of antibiotic such as baytril which will help in early stages.

The pictures attached are very small, so it is hard to tell what is going on, however judging by the color change and flaking there could be a few possibilities. Some parasites and mites can affected the skin and may cause irritation or flaking. Skin issues such as fungal growths, burns from the sun, chemicals, etc, or even bacterial infections may also cause flaking, irritation and discharge to appear in the affected area. Nutritional issues, or injuries from other birds may also cause wounds or irritation that could then become infected. Treating for any parasites, and keeping the area clean and free of debris may help, as well as applying a topical medication to treat any potential infection. You may also want to remove him from the flock for a few days to avoid other birds picking on it and making the area worse. If it doesn't improve, or worsens, having a vet take a look in person is best.

She is definitely in need of an examination by a veterinarian to assess the situation more carefully. Based on the information you've provided, it sounds like she could have some sort of upper respiratory infection, as these often can cause the eyes to crust up and shut completely. Antibiotics and anti inflammatory medication are usually the best bets for this sort of ailment. However, first things first, you'll need to have someone take a look at her to make sure there isn't a primary ocular issue going on instead. Hope this makes sense.

In adult chickens, "wry neck", can be caused by infection, trauma or poor diet. Hen pecking can cause trauma and infection. A poor diet results in a vitamin deficiency, usually E, B1, D or a combination. Have her examined by a vet experienced in treating domestic fowl. Separate her from the flock for now. Feed a fortified chicken feed. Vitamin E should be given daily. Give with the mineral selenium to enhance absorption. Vit B can be mixed in with food or water. Infection should be confirmed and treated with the appropriate antibiotic if indicated.

Thanks for reaching out about Muffy and including a photo. Swollen faces can due to sinus infections, several viral diseases such as pox, or contusions. A veterinary visit is highly recommended as this can spread to others. Isolation of all chickens with clinical signs might help limit the spread. Continue to clean the face and eyes, monitor appetite. Control of biting insects such mites, fleas or mosquitos might limit spread also. Good luck.

Unfortunately, if the eye is infected it needs to be seen in person by a vet (even if it isn't an avian-specific vet) in order for medication to be prescribed. Keeping Karo separated in a warm hospital cage with easy access to food and water, and continuing to remove any debris from the eye can help until you can find a vet near you.

Do not apply any medication in her eye without having her examined by a veterinarian first to diagnose infection or injury. It is possible to do more damage than good if you apply the wrong medication. Once she has been seen by the vet, the proper medication can be dispensed or prescribed.
