What's with the eggs?

[Jabroni]

One of my hens lays eggs with pretty thick shells and they're usually a litlle bit lumpy/uneven but it's getting worse over time. I know this is in the realm of "normal" but this seems to be progressing. Is anything to be concerned about? The eggs are perfectly fine otherwise. Thanks.
