Hello everyone. Yesterday afternoon I went to go check on my flock, and I noticed something very odd. My almost 3 year old Red Sex-Link was flipping and flopping all over the place. It looked like she was trying to do cartwheels. Her eyes were rolled back into her head. Honestly, it seemed like she was possessed. I ran inside and came out approximately 45 seconds later to find her hard as a rock and completely dead. My whole family is baffled. We have absolutely no idea what was going on with her. She had no visible wounds. In the past year and a half, she has struggled with laying eggs. They have burst inside her, but she was always able to pass everything. We started giving her oyster shell as extra calcium, but she never showed any interest in consuming it. This past year the feathers on her rear end were very gross looking and dripped with feces. We tried to clean her up, but she never stayed clean for long. Other than that, she was a perfectly healthy girl. I really need some insight on what could have been going on.
