Not you guys. The hens!
I am patiently awaiting one of my hens to go broody and sit on this clutch of eggs. One of the Australorps (solid black chickens) has been sitting on the nest with the eggs a little longer than she has needed to the last couple days, so hopefully she will decide to hatch these puppies out. Chicks, I mean. Chicken hens don’t have puppies –FYI.
Since my rooster is an Ameracauna, he carries a blue-egg laying gene. So should any of these chicks hatch from my brown-egg laying ladies, I should have green-egg laying offspring.
Break it down (does anyone else hear MC Hammer when they read that?):
White and blue are eggshell tints. The eggshell of either of these two colors are solid all the way through.
Brown shades of eggs are an added pigment. The brown color is usually added to the outside of the eggshell just before it is laid.
All eggshells are either white or blue. All added pigments are some sort of shade of brown, such as: rose, chocolate, buff, copper, and plain ol’ brown. The original eggshell color is easily seen on the inside once you have cracked the egg open. Go try it.
Let’s use an M&M metaphor. Think of the added pigment as paint and the eggshell as the candy coating. All M&M’s are the same on the inside –chocolate, much like all eggs are the same on the inside. The candy coating is the eggshell –usually white, but they are always the same. The food coloring on the outside –be it red, blue, yellow, etc.– is the added pigment to the outside of the candy (or eggshell) at the end of the process.
In chicken eggs, when a brown pigment is added over the top of a white egg, it appears brown. When a brown pigment is added over the top of a blue egg, it appears green.
And that’s the long and short of how you get green eggs. Just incase you were wondering.
