My white crested polish just went limp and died in my arms. She was a little lethargic yesterday but seamed just fine otherwise. I thought she was being broody she was sitting on another's egg since she hasn't layed any herself for over 6 months even though she was only 2 herself. I came over from work and she was sitting on the ground so I picked her up, she was fairly limp and tried to put her on her roosting bar. She started falling off so I grabbed her and her head went very limp. I held her for a second not sure what to do as she just kept going more limp. I set her down and she keeled over. I can't imagine what it was but should I worry about my other bird and chicks that are out there? They all seem fine. .
