One of my hens laid two eggs yesterday morning, but they came out prematurely and were soft shelled so got broken. The hen was somewhat traumatised but came round after about an hour and was eventually feeding and drinking normally again. The eggs came about five hours before her normal laying time, and I assume she couldn't cope with having two at the same time.
So, my first question is whether it is possible for a hen to successfully produce two eggs in a day and with this having happened once with this hen, is she likely to do it again? Any feedback would be good, as I was concerned at first that she wasn't going to survive the experience.
