Hen keeps laying eggs with no shell

[BabeMj]

Hi I have a bantam that keeps laying no shell eggs. The membrane is still in tact but no shell. We have tried giving calcium and foods high in calcium but it doesn’t seem to help. She has trouble laying as well. Please advise

Are you giving 300 mg / day of calcium citrate with vitamin D, daily? If not, do that and continue until she lays a good egg.
Is she a hen or a pullet? How old?

She is about 2-3 year old bantam. 300mg is okay for a bantam
