Ok I FINALLY think I know what is wrong with my hens. After many nights of researching I am almost certain it is vent gleet. I have no vets around here to prescribe me anything for chickens so is there anything I can get for them that is easily accessible? I am pretty sure they are in the more extreme case because there is frequent yellow discharge coming out, so I know I need to treat it ASAP.
I don't have any experience with this, but, found this page and seems like you could work with these suggestions... http://www.birdhealth.com.au/bird/chick-fowl/ventgleet.html
