Acting strange

[BCLFarm]

1 of my 3 year old EE stayed out after dark, I got home within 30-45 min after the sun went down and went straight to coop. Realized one was missing. Found her sleeping under a Bush so put her in the coop on the roosting bar. This am she was sleeping standing up while all others were down and going for day. I’m at work and my son is checking on her off and on before he leaves for work. She is still on roosting bar, laying down rather than standing. But sleeping. She hasn’t laid any eggs since end of May. What could be going on? What should I be checking her for? THANK YOU

How's your hen doing? Has she lost weight?

I just saw your reply. I found her when I got home from work. She did not make it. I still have no idea what had happened. She had not been acting strange at all. Had been eating and running around and drinking. Just didn’t go to the coop before sunset 1 night and passed the next day
