I came home yesterday from work to give my chickens some lettuce and I noticed the one was acting funny in the corner by herself. She was all fluffed up and looked like she was trying to force something out her vent. I picked her up but was not sure what or where to check. She had white runny poop coming out. After about 30 mins it seemed like she got an egg out and this was at 730 and night. She seemed to walk around a little bit more, but when I checked on her in the coop at 10 she was by herself on the corner of the perch. I have posted a few pictures. Let me know if you have any suggestions.
