What is going on with these eggs?

[And now we have chickens]

We have four Easter Eggers. Year and 3 months old. Two of them lay green eggs, the other two lay blue. Over the last month, the blue layers have been laying eggs with major calcium deposits. However, I keep finding completely smashed blue eggs in the nesting box as well as Death Star blue eggs(dented). About 90% of the calcium eggs float in water. Their behavior is normal. Does anyone have any ideas of what might be causing this and how to help our girls get back to normal?

What do you feed them? Do they have free access to oyster shells? How thick or thin are the shells of all your eggs including the ones that get smushed?

They have been getting 20% layer pellets. Oyster shells regularly available. The extreme calcium deposit eggs seem to be thick, but they feel extremely light. The smashed eggs we find are "completely" smashed. The dented eggs have a somewhat soft shell.

What feed and brand specifically? Are the oyster shells fed separately and how quick do they do through it? Do the smashed eggs look like maybe they've been eaten? What is the thickness of the shells of the regular eggs?

Naturewise all flock feed. Shells in their own container, takes quite awhile for them to go through. They aren't eating the eggs. The green eggs shells are typical, no issues with them.

I should also note that they were laying normal eggs all throughout the winter up until this past month.

Educators. What do you guys make of this? Have you ever seen anything like this before in multiple hens in a flock?

Have you added any new chickens to the flock before this started? You say only the blue eggs are affected, not green eggs? Do you have brown egg layers? Did this start happening to all the blue egg layers at once? What do the insides of the eggs look like when you crack them open?

You say some of the eggs float in water. Do you gather the eggs daily?

Can you post photos of your hens and your coop/run setup?

Are they running out of water?

Do you give treats or other foods in addition to the All Flock?

Have you had respiratory illness within the flock?

Any lice/mites or worms?

Any disturbances/drama/stress within the flock?

How much space do they have and how many birds? (Sq ft coop and run).
