What is going on with these eggs?

Clucky had been feather picking and has since been wearing blinders. Which is about the time this started. Maybe it’s stress?

Some of it could be stress.
Feather picking - what is the protein% of your feed?

How much Black Soldier Fly Larva?
Do you provide oyster shell free choice too?

I agree, I'd focus on them eating a nutritionally balanced poultry feed and cut way back on treats. See if shell quality improves.

If they are not sleeping in the coop except when it's cold (winter?) then the coop space may still be too tight for them, poorly ventilated, mites/lice(?), etc.

They get black soldier fly larva, fruits & veggies.

There was a feather picking issue (see reply to other question in this thread). Their run is about 100-120sqft. (Sand) Coop is adequate for the four girls(5’ wide 3’ deep 4’ tall)(well ventilated), they sleep outside in the run on top of the coop through the spring summer and fall.Two nesting boxes.

Mine have more speckles and calcium spots since we culled the roosters and got a new one. One has even acted broody for almost 2 months. Stress changes a lot in chickens. A handful of treats a day won't hurt, but should be mostly grazing or on pellets. I even put cut grass in the run. Try changing one thing at a time to see what helps.

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

Very interesting as I am experiencing recently similar issues. My chickens are 2 - 5 years old, have been getting the same Nutrima feed, get additional calcium and have never had this issue until recently.

Some people give all flock feed because they feel that more protein is better. Not necessarily. Excess protein can strain the kidneys and also cause excessive nitrogen excretion which causes more ammonia to build up from the manure. This is not healthy to breathe in. Laying hens need 16-18% protein. When they are molting and growing new feathers, then 20% protein is better. New chicks, which are growing rapidly, may also do better on the higher protein. Layer pellets have more calcium and other minerals that laying hens need than the flock pellets. If you want to keep using the flock pellets, you can supplement with calcium, such as crushed oyster shell.

Some viruses might infect the oviduct and shell gland, causing glitchy eggs. You might be dealing with this.
If no other symptoms appear, and nothing is wrong with the chickens diet, the hens will heal on their own in a few weeks.
