I have a buff orpington hen that needs help. she was missing for a couple of hours. when I found her, she was sitting by herself. I did a look over her and she was making a weird noise. the bottom of her right wattle is swollen, she has a kind of a crust around her right eye. when she sneezed there was like a bloody snot. it seems like she can't breath through her nose. when she breaths it sounds like she has something in her thought like mucus or something. please help me figure out what's wrong with her.
