Assuming this is not a joke - and the object was truely laid by a unfertile hen.
The outer covering & layers indicate it probably was a egg at some time, during development of the egg in the ovaduct the yolk & white are surrounded by an tough, durable, rubbery, orgainic matrix that later calcium carbonte is added to. This inner layer of the eggshell is what is seen here, in the outer layers, repeated layers, a build up of this normal tissue due to the time spent inside the ovaduct. inside the object is the remains of what was once a yolk (yolk is the same smell as chicken meat!!), or course several eggs may have combined as the shock of her injury brought a halt to all egg production. So any & all eggs in the ova duct were formed into this mass, extra layers of the organic matrix eventually formed around the mass, and when she recovered enough, it was all eliminated. What happened to the albumum (white) you ask, good question. The protein was reabsorbed and also as much of the yolk as her system could dissolve to help her to repair her damaged tissues. What you see there is just what was not dissolved & absorbed.
This is all due to her trama and near death experience. I predict a full recovery in time.
