I have a white leghorn hen that has always been very consistant in her laying size med/large forever color white timing every day 9:07 am everything. I have changed nothing for her. Today she left me an egg that compares in size to a duck egg. What is up with that? Is this something they do sometimes? I am in my first year of hens. So I am still learning and observing everything. She does not appear to be hurt from this. yes I was concerned and checked her over. that seemed like trying to push a bowling ball through a garden hose. Sorry for the visual but I was worried now I just need answers.
