This is a subject right up my ally :biggrin1:
gymfresh, what do you think is beneath the brown shells? I can tell you.. the exact same thing that is beneath the white and, blue, or green shelled eggs. The contents of the egg is not affected at all by the exterior color. There are lots of brown eggs in many grocery stores in the US.
When I was doing a "Farm Day" education program, I would do about 4 demonstrations during the day. For the 1st demo, I would take a white, brown, and green egg, and ask the kids what they thought the inside was going to look like. Many of them had the same assumption as you.
I would take and break each egg in a small clean salsa jar, and they (and some adults) would be shocked that they were all exactly alike.
For the rest of the day I would ask the kids to guess which shell went with each jar. (I had previously written the color on a piece of tape and stuck to the jar, which was then turned to the backside)
The general rule is that if a chicken has red ear lobes, it will lay a brown egg, and if it has white ear lobes, it's egg will be white. Of course like the rest of Mother Nature, there are acceptions.
O Y and Aqua Eyes, I am thoroughly impressed :smile:.
A few totally uselss facts for most here....
Araucanas (as known in the US- Britain Standard varies) were originated somewhere in South America. Their true shell color is a turuoise or blue. They were first imported into the US in the early 1930's. They are completely tail-less, missing the Uropigium (or Coccyx) which is what the tail feathers grow out of on other birds. Although there are others, they are the most common tail-less chickens. Those "Old timey sideburns" are called "tufts" and are feathers that grow out of the side of the face near the ears.
There is also a breed called the Ameraucana that also lays the turquoise or blue eggs. These were develop in the US in the 1970's by breeders that did not want to contend with the fatal gene that accompanies the tail-less gene. These birds not only have a tail, but the tufts are replaced with a "beard and muffs", which are downy like feathers encircling the lower side of the face and front of neck, much like a Amish beard.
The blue egg gene is dominant,so either of these breeds crossed over other breeds produces a whole range of different shades including blue, green, and pinkish hues. Most "Araucanas" sold in hatcheries are just such crosses and correctly referred to as "Easter Eggers".
The "chocolate colored eggs referred to by Aqua Eyes come from French Breeds such as the Maran, Barnvelder, and Welsummer, to name a few. There are actual competitions based on the darkest color being the most desirable.
Bettcha didn't know and didn't care about the above, lol :tongue:
Don't often get to talk about these kinds of "Cocks" and Hens on the big cock board. lol
