A few years back I was helping Brinsea incubators with their displays and demonstrations at the Mother Earth News fair when it was in Pennsylvania. I had the eggs all ready to hatch but the one problem was that most of them were brown! When demonstrating candling eggs and incubation equipment you can see inside the egg most easily if it's white or cream colored. The darker the shell the harder it is to see inside.
I had brown and white partially incubated eggs with me, but the white ones were from the silkies, so they were rather small white eggs since silkies are bantam sized. This sent me on a quest to find a standard sized white egg laying breed. I found several!
Lots of people that raise chickens for eggs like to pick and choose their chicken breeds so that they have different colored eggs. It's often referred to as 'a pretty egg basket' or 'a rainbow egg basket'.
Chicken eggs come in many colors the most common are blue, green, brown and white. Admittedly, most people are only familiar with white and brown eggs and many people don't even realize you can own chickens that lay white eggs!
I was once told that only egg farms are allowed to have them. lol I should probably add that to the post I wrote about things non chicken keepers believe...but for now lets move on to the white egg layers!
There are several breeds that lay white eggs and they are all readily available from hatcheries and private breeders alike. Just like brown eggs come in various shades though, white eggs come in both pure white and off white or cream colored.
