I let the girls out this morning and saw them all jump out of the coop. This afternoon I went out to collect some eggs and noticed one hen was dead. I noticed a week ago that her crop was a really deep red color. I just assumed she was getting ready to start laying after the winter off, along with the others. I just finished an autopsy of sorts because I noticed her vent looked like it was bulging. My first thought was she was egg bound. When I cut open the vent, water/diarrhea gushed out. Her vent had to be sealed shut if that water wouldn't come out under the pressure. Any thoughts on what could've happened? Should I worry about the other 23 hens?
