Hey, I've had chickens for a couple of years now, I had a one year old Welsummer hen called Leah, she seemed fine and normal, she was really friendly and would eat off my hand and follow me around the garden. Unfortunately she died this afternoon and I have no clue why, I want to make sure it wasn't a disease or infection that could spread to the others in the brood. She seemed healthy and was eating and drinking, she wasn't walking weirdly at all and didn't look as if she was in any pain or discomfort. She was hand raised by me so I can say that she hadn't started to lay but I didn't know whether she would or supposed to start to lay. I noticed when she was dead that her area around her anus did have blood around it as well. Can anyone please tell me the cause of death? And if its a disease/ infection how I can cure the other chickens? Thank you for reading and if you have any information please do say.
