Yup! I often get stretch eggs. I get completely round ones too. and textured, and spotted, and have even had a couple with double shells. Hens are funny!!!
My EE stopped laying for a couple weeks and the first egg when she started was a little bumpy, like it had been a squeeze to get it out - not as good as yours, though!
My EEs, no. However that's the almost identical in shape to one of my turkens, except hers are pink and (for reasons I can't decern) shiny, as if they'd been polished.
