My young duck has been laying wrinkled and soft eggs

[Therubysaurusrex]

One of my female Pekin ducks has been laying some soft eggs recently so I’ve started giving her crushed oyster shells however today I found a wrinkled hard egg. I’m very confused as where I’ve looked up what it could be I’ve found that it’s because of old age however my ducks only 6 months old.

Has she just started laying ? Sometimes early in a laying cycle they lay strange eggs.

She started laying a few weeks ago so maybe
