We bought a POL Marans pullet at 7 months old. She laid her first egg after only a couple days in our care, but the shell was super soft. I came in the coop (I had a feeling she was going to lay) and much to my disappointment the egg had been opened and eaten by her and some others. It was obvious who participated because their beaks were covered in yolk 
2 days later, she laid an egg before we came to open the coop in the morning. It was soft but unscathed.
It has now been 10+ days and not an egg to be found. I check on them very often and Donna (the Marans in question) hasn’t been singing her egg song or making any noise/behaviour indicating she has layed. The other time she layed in the day it was very obvious she was going to.
All of that to say, is it normal she has stopped laying? Apparently the rest of her breeding group hasn’t started laying yet. She otherwise seems in great health, energetic with good comb colour, eating as normal.
