Breed and genetics determine the color of the hens egg. The part of the oviduct called the Isthmus is where the membranes of the inner shell are deposited, for some select breeds like Araucana this is where the color of the egg shell is first deposited. Calcification of the shell takes place in the uterus and at this time and for most breeds of chicken the color of the shell is acquired in the uterus just prior to being released to the vagina and released through the vent.
Yes. Feather color does not effect the color of the egg shell, breed determines the color of the egg.
yes but so do non-organic chickens! The breed of the chicken determines the color of the egg shell. Nothing else affects the color of the egg shell.

no
The thickness of the shell is not determined by the color. The age and health of the bird determines the quality of the shell. As a hen ages, her reproductive system cannot maintain peak shell making capabilities. Her system will no longer utilize the proteins and calcium she eats the same as when she was young. Eventually her egg production comes to a halt.
egg shell color slightly yellow
it is a "dirty" white
You cannot change the color of the egg shell, genetics are pre determined at hatch and the color of the shell is not effected by feed. You can change the color of the yolk with feed but not the shell itself. The color of the shell is due to a bile duct secretion as the egg is forming in the oviduct of the hen.
the shell of an egg
The multilayer hard shell of the egg of a White Leghorn chicken is white. The inside is the same color as every other chicken's egg. The shell is white because the Leghorn does not have the color genes to have blue shells or brown applied to the outer shell layers.
The colour of the egg shell primarily depends on the mother's breeding.
Look at the bottom of page 24 in the middle. The egg shell is a bluish gray color.
