I have an 8 month old Columbian Wyandott hen, who as of yesterday was at the top of the pecking order and completely healthy (or so I think). Up until they went to roost last night, she was crazy with her bullying behavior, eating like crazy, happy as ever. This morning, I found her in a nesting-like position in the middle of the coop run on the ground, unmoveable even when I approached with breakfast. She is all fluffed up now, her comb has gone from dark red to like pink, won't eat, won't really move. When I pick her up, she closes her eyes and doesn't fuss. I would describe her as very near lifeless. No discharge, no molting, no bugs to be found, poop is semi-normal, vent is not inflammed or prolasped. ?????? Are these symptoms common to a virus? Is this a broody behavior? Could she be eggbound with such listless behavior? Greatly appreciate any ideas or suggestions on what I should look for.
