Our beloved Bean died this morning. I found her on the laying nest dead. She had a bloody-looking round thing coming out instead of an egg. She was only 3 years old. We noticed yesterday that she was walking a bit wobbly and sitting down a lot, but the day before that she was running around with the other chickens. All three of our 3 year old chickens stopped laying eggs about a month ago . That seems a little early from what I've read. Is it possible they all have some kind of intestinal disease? Thanks for your advice. Here are some specifics about her: She was 3 years old, Red Star, no idea on weight. She only exhibited the symptoms in the last day or two (acting tired and sitting down and wobbling a lot). Her egg production was down--we don't think she was laying anything for the past month. One other bird stopped laying but seems to be ok. No injuries other than what I mentioned with the bloody looking protrusion. She was eating ok but not vigorously up until her death. Her poop was normal, possibly on the running side. We didn't administer any treatments and don't have any photos. Her housing is a small coop she shared with two other birds with straw as the bedding.
