I live in Hawaii we have wild chickens all over island, we have a small group of chicks living in our yard (teenagers on therye own). Today I found 2 of them wondering around completely blind. We've had this disease spreading in neighborhood locals here call it chicken pox. They usually get it in one eye it will swell up they lose the eye normally (we had in hen survive after losing 1 eye) but a lot of times it spreads to both eyes and sometimes in the throat. Anyways both chicks eyes were completely swollen shut completely blind one passed away today he had a swell in throat also, but his brother is a lot better. But he won't eat I've given some vitamins in his water advice?? Is this a form of mareks??Spreading around island fast! should I try syringe feeding him? Il post photo in morning
