What is wrong with my hens diet?

[Moody]

They get nutrina nature wise layer feed, free range for 2-5 hours daily and I just started DE around the coop and in their dirt bath area how can I fix this?

 

[Southern by choice]

Are they raised bumps or are they mottled in color?
The brown looks raised, the green looks like it may have the mottled.

 

[Moody]

Correct the brown is raised and the green is mottled. I read something about bad diet or calcium issues.

do you free choice oyster shell because I have had eggs like that before and calcium fix it
also it seems to happen when the hens get older

I agree with jk47, make sure that your hens have access to plenty of calcium. I also give my chickens red dirt when they are penned up. There is something about it that makes them thrive, I can't say what it is exactly but an old timer told me about it.

Ok thanks all. I was thinking I could just give their shells back to them for calcium but I will get some of the oyster shell

Every time I clicked on to respond there was an interruption. LOL
Calcium would be my first suggestion too.
You can also add sea-kelp to their diet.

Sometimes illness can cause bumps. The see through mottled eggs can also happen when you have inbreeding. Hens that are inbred can have issues like this. Rarely will eggs like these hatch if incubated.

Birds that are stressed perhaps from sudden penning for a long period when they were originally free ranged will start having egg issues.

Check for worms also. If they have worms it robs them of the important nutrients they need.
