Leghorn hens

I think you are right about that. Since she has been eating well and not showing any other signs - she can run like the road runner she's fast..lol- her coat and her wattles look healthy too.

LOL, I've owned White Leghorns and you're right, I could never catch them. I had to use a fishing net. I had to cut both their wings feathers too, they easily flew over our 5' foot fence.
If your hen had a disease, your other birds would be sick as well. It doesnt take long for Coryza, MG, ILT or IB to infect birds.

If you can ever catch her, it would be good to see a clear close-up of her left eye. I am glad that she has no symptoms of a disease except for the swelling of the face. That can be due to an swollen peck wound, and also, a tumor or cyst. At night after they go to roost, you can pick her up and examine her. Feel if the lesion is hard or soft. Peck wounds can become abscessed. Hopefully, it is not anything contagious. So since she has no other symptoms, I would not separate her, and perhaps, see a vet.

Since it is actively growing it is going to become an issue sooner or later. Whether it is a tumour or localised infection is hard to day but sinus infections are quite common in chickens and cause swelling around the eye. If veterinary treatment is not an option, I would be inclined to try flushing the eye with a weak saline and see if you can flush anything out. Chicken pus becomes solid. It can sometimes be expressed out of the eye socket or require external lancing and extraction. There are numerous You Tube videos of these techniques and they are pretty brutal to watch but if these infections are not dealt with they will eventually become life threatening. It is extremely unlikely that antibiotics will deal with any pus that has built up in there and that will be a source of reinfection if it is not removed, so it really needs to be cleaned out.
If it is a tumour which is growing, her days are numbered anyway, so you don't have a lot to lose by opening it up to see if it is an infection or tumour. I would be prepared to euthanize her if it turns out to be a tumour.

A clearer picture of her eye would help to distinguish between a tumor or respiratory disease. MG is a lot more common than coryza, and E.coli can also get into the eye causing a swollen infection. Her sinus region looks swollen, but in the picture, it is hard to see the actual eye. Do you see any evidence of a peck wound on the face.?

 

[rebrascora]

I agree, a close up of that eye will give us a better idea of what may be going on.
