I had a 10 week old sebright bantam chick die a couple days ago. It was a pullet. She was outside in my "Grow up pen" with 6 other bantam chicks. I got her locally at the age of 5 weeks. But when I went to feed them one evening she was laying down so I picked her up. She was still alive but she kept twisting her head around. Her breathing was weird and her eyes were half closed. I knew she was going to die so I held her until she passed away. (Which was about 10 minutes later). But before she died I put her on the ground and she started beating her wing on the ground. It was very strange and all the chicks she was with are fine. Her bottom beak had always been longer than the top, so I trimmed it with clippers every week. What happened???? Please help!
