Thanks, all. I will get the oyster shell going, keep up the ACV, try to keep her cooler, and see if we can't turn this around.
God bless,

PS - the hen's name is Mary. Her RIR buddy is Martha. They are good hard workers. ;-)
I just watched my older BR lay a paper-thin-shelled egg, turn and start eating the yolk. I took it away from her and cleaned out the nest. It has been pretty hot here, until today (mid 80's today) but I think I'll add some oyster shell to their diet, just in case. She and the other chickens...
