It's normal for some pullets to have shelless/thin shell eggs. She'll work it out.

Soft shells or shell less eggs in more experienced layers can be caused by a number of things, such as nutritional deficiencies, a parasite infestation, certain diseases, weather extremes, stress... See here for more detailed info and causes:

Thank you thats very informative but im still lost they have good nutrition as I said they free range have layer crumbles grit Oyster shell pleanty of water I give them veggies oatmeal yogurt corn meal worms black sunflower seeds as treats. We clean the coop regularly I put de down everywhere every single time we clean. As for stress I added 3 more to the flock back in March im not sure if this could be the problem or even how to narrow down who it is.. theres 2 nesting boxes there were 3 but everyone insists on using the same one. Im just dumb founded

Have you treated the flock for worms and external parasites such as mites and lice with a chemical product at any stage? DE is good for certain things, but it's effectiveness in parasite control is limited.

What is the weather like by you? Any big changes in weather patterns recently?

Feed wise, have you always fed them what you listed above and in the same ratios? Maybe cut back a bit on the cornmeal and the oatmeal so they'll eat more of the more nutritious layer feed. See if that helps?
