I noticed yesterday as I was collecting eggs that one of my girls was nesting rather late in the day. I went to check on her early evening and she was still in the nesting box. She appeared to be a bit lethargic and when I removed her from the box she did not put up any fuss and immediately laid down where I placed her. I checked her vent and it's clean, doesn't appear swollen but was pulsing a bit. I believed she stayed in the box all night and this morning when I checked her she was still there. She will eat if I bring food to her but will not drink water. Any advice or information would be greatly appreciated.
