I have a GLW and she started laying a few weeks ago. Her first egg was a double yolker, she has had a ghost egg (had a yolk), and generally was laying daily, or close to. Then she had a slab sided egg. I know it was her because she's my only brown egg layer so far. We have a 8x10 run, 4x8 coop, with a total of 6 full sized pullets, and one 15 oz serama hen - she's the boss. They are fed Nutrena laying crumbles. And they are on grass, free ranging in the evenings. But they are in a tractor. So she has had two slab sided eggs, both had very watery whites, and then both yolks had half of them being marbled with creamy white in it. We got her at three weeks old. And a week later, we brought in the other babies. No one has been sick. And everyone gets along. Is there something wrong? Or is this something that is a pullet thing that she'll grow out of? Are the eggs safe to eat?
