No the eggshell of brown eggs is not thicker than the eggshell of white eggs.
Neither. They are exactly the same. Eggshell color has nothing to do with the thickness of the shell. The thickness will vary depending on health and diet and age of the hen.
The male has white stripes on his shell and the female has brown stripes on her shell.
Both contain bone but most turtle shells would be harder than an armadillo's shell.
No. It will stay brown - the color goes all the way through the shell.
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 color of the egg shell has no bearing regarding the allergy of an individual. Brown eggs may produce an allergic reaction quicker than white eggs.
A boy has white stripes on his shell and a girl has brown stripes on hers.
White stripes on a shell means it's a boy and if it is a girl it has brown stripes.
It's harder to spot a cow that is more solid coloured than one that is spotted with black and white or brown and white. The white can be picked up by the eye much faster than an all-black, all-brown or all-grey cow.
