Eggs at differnt stages but due the same day?

[americana-chick]

Some of my eggs that are due on the 9 look like they might be at differnt stages.. some show a lot of free space, others just a little and the rest have barely any space left. Does this mean that they might hatch on differnt dates..? they are all still moving

hmm..Mine look like that too. I was wondering if maybe the eggs are slightly larger than normal for that type of chick-making more room available for some. Some of mine are completely darkened all I see is air cell. Not sure but I know of only two eggs that will for sure be behind a day or two and that was my two silkie eggs. Good thing I put those in too because my girls stopped laying:-( 4 hens and no eggs for a week today:-( that rots!!!
