 for Fluffy! 
It is a good sized egg she has laid there. Is she a bantam or standard size? I've found my standard size WCB hens lay much bigger eggs than my bantam size.
I totally agree on the they will lay when they are good and ready and not a moment before. Some polish are just not good layers and never will be, it all depends on the individual lady. I have a frizzle hen who has laid only 5 eggs since the summer of 2015. She was quite a sporadic layer to start with but after she went broody (june/July 2015) and hatched her chicks the eggs have pretty much dried up.
