Soft Egg Shells in Pullet

[karenmragan]

Hello, thanks to anyone who may help me figure this out. The issue is with a 5-month-old Austra White pullet. I have caught her several times lay a very soft-shelled egg in the middle of the coop floor; which promptly gets eaten. This has happened in the morning and in the evening.
She is on a diet of 18% starter mash with free-choice oyster shell, along with 1/4 acre of green pasture to forage. This is the only hen in the flock who seems to be experiencing the issue. I should note also that most of her eggs are normal, but this has become too much of a problem to ignore.

I know some people might think this is too much trouble, but since I have been doing this I have had no more soft shells. I would mix up their feed with a cucumber, grape tomatoes, cabbage and sometimes unsalted corn from a can. Also I would cook eggs and put the shells in the microwave for a couple of minutes, them use my ninja to crush them to a pulp. I would do this to each ingredient, then mix it together. I give them a few big spoonfuls and put the rest in the frig and give it to them once a day til it's gone. They love it. I also put grit in the mix to but only after everything is well mixed. Hope this helps.

Is the oyster shell being consumed?
You might try confining her in the morning and giving her extra calcium.
