laying thin shells eggs
Hi! Welcome! If your hen has just started laying, it's not at all uncommon for it to take a few weeks of erratic laying for them to get all the parts of their egg factory synchronized. Shelless eggs, double yolkers, fairy eggs, soft shells.
It's important to be sure they have enough calcium. Free choice oyster shell is almost a must. Are you feeding layer or grower? Layer has added calcium, but often isn't enough.
When having poor quality eggs, it's prudent to limit treats, fruits, veggies, scraps free range to ensure a well balanced diet. Free choice oyster shell in addition to her balanced feed should help her get her factory in line.

Best of luck.
It's just too soon to be concerned about weird eggs with new layers. Make sure their diet is good, as mentioned above, and give them more time. Egg shells don't substitute for oyster shell as a calcium source for high producing hens. There's research that shows that the egg shells dissolve too fast in the hen, and the calcium isn't available to her when she's making the shell. Some birds will be poor layers, but more be patient here. mary
