I noticed yesterday that my almost one year old banty had a pale face. I was just out there a bit ago and noticed that it's nose was all clogged up and crusty. I was able to pull away all the crust and it's nose was a bit runny. I'm guessing now that it must be sick. I listed to it's breathing for a long time and the breathing sounds really clear. What should I do besides separating it from the others? What do you think might be wrong with it?
