This is my hen. I have so many I don't know if she has been laying or not. She is just over a year old. I found her like this when I got in from work and took this picture just a few minutes ago after I couldn't find any info about it on the net. Closest thing I can come up with is impacted egg? Like I said, I have lots of chickens and most of them have stopped laying since so many of them are molting right now so I can't say if she has been laying or not. When I lifted her tail to get a better look she started to pick at the vent area and thats when I noticed she has it bloody.
