Hen wasn't eating yesterday, died this morning

[The Birb King]

I noticed yesterday one of my Ameraucana hens was acting strange. She was unbalanced, staying inside the coop, and not eating so she felt very thin. I also noticed she was having green diarrhea. Last night she could barely get up on the roost, and this morning she was dead. No one else seems sick, but I'm still not sure what the issue was

Very sorry for your loss. How old was your hen, and had she been molting or recently laying eggs? If you are in the US, you may keep her body cold, but not frozen, and send it to your state vet for a necropsy to get an idea of what she may have died of. Some people also may do a home necropsy to look at and take pictures of the abdominal organs. There are necropsy videos online for help, and most here would offer opinions about pictures. Here is a list of state vet labs:

She was about a year and a half old, so pretty young. I already got rid of it so I can't do a necropsy, but I wouldn't know what to be looking for anyway
