Egg Without a Shell

[MontanaChickenLady]

I have a 3 year old Black Austrolorp that has recently started laying eggs without a shell. She's always been a dandy egg layer. I have no idea why this is happening and what, if anything I can do. She is getting layer feed with oyster shells mixed in. She seems to be fine otherwise and is getting along as usual with my flock. If you have any idea what is causing this, I would appreciate some insight. Thanks!!!

It can happen as a hen ages.

...and she may be getting ready to molt.

Causes for soft shelled, or shell-less eggs can range from nutrient deficiency to stress, to a parasite infestation. There's a list of the possible causes and more info here: https://www.backyardchickens.com/a/common-egg-quality-problems
