We came home today and found one of our hens dead. She was in one of the nesting boxes. I can't see anything wrong with her - I believe that it may have happened last night - not sure - we have been at the county fair all week coming and going and not at home as much. She was about 1 1/2 old and seemed very healthy. I didn't notice any strange droppings and I checked her for mites. We have the other chickens out of the coop right now but are planning on checking them. Poor Annabelle was my daughter's pet and she will be missed. Any information that you have would be helpful.
