Where are you located?
How old are they and long have they been laying? How long ago did this start?
Any other symptoms?

give them some calcium i've never heard of completly shelless eggs but if my chickens egg shells get weaker and softer i give them a calcium supplemeny in their food. it looks like little white rocks that you just mix into their food.good luck

The OP said they're giving oyster shell and layer feed. I wonder if it happens occasionally or every time. Shelless eggs happen occasionally but if it's a regular thing, I'd be worried as it's possibly related to a virus. Calcium can't fix that.
Raw apple cider vinegar helps them assimilate the calcium.
