A couple of days ago I realized that one of my girls was hurt. I examined her but found nothing external but I put her up any way to see if forcing her to be quiet would help. It didn't. She died today. I went down to check on her earlier and found that she had lost whatever battle she was having. I removed the barrier and returned to the house to get what all to remove her body. By the time I returned there were three birds hunkered down around her body so I left to give them whatever time they needed. When I returned the next time her mate was hunkered next to her. I'm not even sure he'd let me near her so for the time being he can stay where he is and if I have to wait until bed time to remove her then I will.
