Thanks.
It WAS NOT Gladys who passed away. That's what surprised me most. Gladys is hanging in there - my old girl. One of the younger hens passed away. So sad.
I'll keep an eye on the other girls to see if anything else is changed with them.
I posted a few weeks back about my older hen, Gladys, who was lethargic/sitting around/breathing heavily but still eating and drinking properly. She's progressed over the past few weeks, but still occasionally will "rest" in the hen house.
Today I walked out to see what the other hens were...
