I have some buff orpingtons and ameracauna pullets 10 weeks old. They all have some very small bugs on them and also some tiny egg-like dots up around on their face and head, some have raw looking spots around their eyes, and one or two of them have some snotty looking stuff and bloody stuff coming out of their nose. One also has a matted eye that looks full of fluid with some bubbles in it. any help would be greatly appreciated. thank you.
