I lost a beloved hen in my flock tonight, Daisy. I was away from the house and come home to find my family trying to help her. Appearently, they found her lying on her side, barely responsive next to our coop entrance. The other chickens in our flock were all surrounded around her as if they were comforting her or protecting her. They carefully relocated her to a tub lined with a towel indoors. I immediately came home after hearing of this, and quickly began to take action. She was on her side, and was largely unresponsive to touch. She was barely able to support her head, and keep her eyes open. I syringe fed her sugar mixed water in very small amounts, and she was able to gulp down whatever I gave her. I made sure to only give her a small amount to avoid choking. I splashed a few drops of water across her head, she would widen her eyes for a small amount of time, and then slowly close them. She was unable to support her neck. I did not want to lose her, and caressed her supporting her neck. Very quickly, she started kicking and moving her he'd in pain. She became completely unresponsive, and a stringy/viscous liquid dripped from her beak. She had died in my arms tonight. I buried her and said a prayer for Daisy, as I love all my pet chickens like family. I am very worried that there may be a disease or illness she caught and spread. I want to take immediate action if I can narrow the cause of this. Thank you.
