I have two white leghorns that were laying normal beautiful eggs and now all of a sudden they're laying eggs without shells not sure what to do please help
Soft eggs can be caused by low calcium, stress, heat, and beginning the laying cycle and when it winds down, make sure to keep a bowl of oyster shells available at all times and try to keep any stress down, it's not that unusual for a hen to lay a few each season.
^^^ Ditto Old Hen covered it. Be mindful of table scraps or other feeds that might deplete calcium levels.
Take a look at this article in the Learning Center of some of the odd things that can happen with eggs and the possible causes: https://www.backyardchickens.com/a/common-egg-quality-problems I've referred to this information more than once and it's been helpful. Maybe it will be for you too.
