Well I opened her up. Inside her oviduct, I did find 3 small ready to roll eggs- shelless and about 1/2" diameter.
No evidence of shell anywhere in her body.
What I did find was lots of what looked like lightly cooked egg yolk all throughout her egg system.
Her crop wasn't inpacted, though it did contain some food. Further down the digestive tract, the food was ground and her gizzard appeared to be working fine.
The day gets better!
I went out and buried her in the back yard; my daughter picked some flowers and placed them on her grave. We all had a moment.
Come back in, go to Church, come home and Dang! Cable's out, along with phone and internet.
Call Comcast, a guy comes a out, walks around, inspecting the lines and says "have you done any digging lately?"
He's standing there, looking at Jan's flower-covered grave.
Me: "uh, yeah, I guess I have...."
He was a real peach, offered his condolences and did the reconnect without a charge for my bonehead move.
What a day!
Thanks for all the kind words. If anybody's got any idea what happenned to Miss Jan, I'd be obliged.
