I recently got some eggs from the farm and I noticed some of them easily crack, break or leak and have weird-looking shape.
This doesn't mean the nutrient gotten from such egg is reduced or is of lower quality; Its only showing signs that the hen is either sick, aging or lacking some nutrients in it feed. That reminds me, the weather has not been chilling during the past few months; the level of stress also affect production.
I apologize for the poor quality of the image. It was taken at night.
