So weird... When I left for work this morning it was pouring out. It was supposed to be heavy rain all day so I let the chickens stay in their coop. Nothing has ever gotten in there - it is pretty impenetrable. When I got home I asked my 6yr old to let them out. Poor choice. One if our 3 two year old hens was dead in the coop. She doesn't have any injuries. They have all been acting completely fine. I locked them in at around 9pm last night. We lock the coop during the day because our trouble-maker goats will get in and eat all the chicken food. The hens fall asleep on the fence or pergola next to the coop and I pick them each up and put them in on their roost. It was about 5pm this afternoon we found her. There is nothing broken on the coop. All doors and windows have individual chain locks and none were disturbed. The one thing I did notice was that there are 2 spots one on the wooden gate and one on the post right next to it, that have seemingly fresh (I can't say 100% though) claw marks. They are up high like something maybe climbed over it. There are scratches on each of the two marks. They look too close together to have been made from the chickens climbing over it - they have gone over it before if the wind blows it shut. The hen is one of my Americaunas and they are both super skittish, to the point that I thought one was going to die when I caught her to clean some poop near her vent one time. Is it too "out there" to think maybe a racoon was trying to breach their coop and she died out of fear? That is all I can think of for a cause at the moment. I am going to do some more sleuthing though...
 
If you still have her did you do a examination of her. Stomach,crop,skin,vent,inside her mouth,waddles Ya know really looking over her right down to the skin. I’m the type of person that it would drive me crazy not knowing. And as much as I love my chickens I cut them open and do a kind of necropsy. If she was a meat bird they can drop dead due to genetic features that make them grow fast. You said 2 yrs. old what breed was she?
 
I do still have her. I did a quick look over but my 6yr old was right there so didn't want to poke around her much. She's in rigor so has been dead a few hours. I will check her out better when he gets distracted with something or goes to bed. She is a Wheaten Americauna. Maybe I will watch one of the videos/articles some BYC folks have referenced about performing chicken autopsies. I am not too squeamish and yes, it is driving me crazy. Plus I have 12 new chicks in a brooder so need to find out if it is something I have to treat the environment for. Thankfully they haven't been around the older hens at all. I did find a couple live worms on the ground outside the coop but did some research to make sure they were young earthworms - just to be sure. They were segmented and tan/brown. And none were in the coop or in poop. Just paranoid I guess. It rained all day so makes sense they were out.

Any suggestions on the autopsy process?

Thanks so much!
 
I have to work myself up to this... I know it is for the best but just unsure. I'll do the external exam first and post my findings. I just locked her sisters up for the night. Checked them for lice and nothing. No injuries. No odd behavior. No diarrhea. One is molting but fine. Checked the coop well. No weird poop or worms. No sign of a break in. Only thing I found was a tiny field mouse who may have run in when the coop was open - I couldn't shut one window for a long time because of the humidity but was able to close it the last few days.
 
If you do a necropsy, please take photos and share them here. A few of us are rather more experienced at it than we should be and could maybe help you in determining a cause of death. With a sudden death like this I would be looking for any fluid or blood in the abdominal cavity, how much yellow fat is in and around the abdomen and the state of her liver. Reproductive disorders are also very common in birds 2+yrs old. Egg binding should be easy to diagnose. The fact that you had a bird possibly this one, with soiled butt feathers recently suggests some abdominal swelling which is usually an indication of reproductive ailments but there can be other causes. Can you also take a photo of your coop and run as it is very difficult to envisage what you are describing as regards where the claw marks are etc.
