I was wondering if anyone knew how long it takes for a bird to lay the egg like when they are in labor?

The actual egg-laying does not take long at all, although my hen always laid her eggs at night so I never actually timed it. If I had to make a guess I would say no longer than 15-20 minutes, max...but if anyone has timed it I'm sure they'll post. If it took much longer than that, the hen would probably be worn out or in great distress. She then needs immediate attention. I say that because generally if you have an egg-bound hen that home care does not resolve the laying of the egg within an hour, a trip to an avian vet is called for so that she does not die.
