Verschluß der Legeröhre bei Hühnern?

I would say “yes.” One user Huehner was once bound egg and me a “seat bath” in warm water and tranquility in a box, the egg came out on the natural way. But Penny was uncharacteristic calm and I have honed from others that they have lost their hen if the egg could not come out.

And yet another thing: never toss the egg inside the hen, the jagged egg shell can hurt it very badly.
