Hi I'm new here and I need some help. I have an adult hen (austrolorp) 2 years old that was perfectly fine yesterday. When I came home from work today, she was inside the coop wheezing and gasping for air. She stretches her neck up as she gasps for air. As I was trying to check her throat, she bit me in the finger so hard that it bleed. I thought maybe she had something stuck in her throat, but I couldn't see anything. She's not eating or drinking right now. She just sits there wheezing and gasping. I have 13 hens and she's the only one acting like this. My hens are very healthy and I am very concerned about her. Does anyone know what could be wrong with her? Her name is Lotte and she's named after my mom, who lives in Germany, that's where I'm from. Please help.
