Egg white then egg yolk

[Chicken girl 15]

I have 18 hens just over a year old. I get between 13 and 18 eggs a day, have been for many months. However for the last week I have been getting 1 egg white with no yolk and no shell. The next day it's 1 yolk no shell no white. Back and fourth. The get an all flock grower with oyster shell on the side. I have narrowed it down to 1 of 5 girls as I have 3 breeds all laying different shades of egg. What causes this strange egg factory mistake? Can I help her or do I just keep her happy and fed until she passes?

Getting small eggs with no yolk can be common in new layers, but I don't know why they would have a yolk without the white or albumen. It could be some defect in a part of the oviduct. Hopefully, it won't last. TheChickenChick has a good article about common egg problems.
