Odd eggs being laid are they safe to eat

[Cwbarka]

Our 1 and a half year old Easter eggers started laying large odd shaped eggs a couple weeks ago. Would love to know the cause and if they are still safe to eat and treatment options if necessary. They are free range non medicated. The egg on the far right is a typical size egg for reference.

Sure, these look like calcium hiccups to me.

It wouldn't hurt to crack them individually in a separate bowl, so that if there's something funky, it doesn't affect any other previously cracked eggs.
