Yep, they come from the chicken, which, by the way, came first.
Watch this video and realize that this chicken does this every day for years before she is too old to lay any longer.
Certain breeds can lay upwards of 300+ eggs in a year.
Some lay Brown Eggs, others White.
The color of the egg in no way affects the nutritional value of the egg.
However, what is FED to the chickens can greatly affect the egg.
We recommend chickens be fed a non-GMO, no-antibiotic food source and be allowed free-range (which means they can wander around and enjoy the sunshine, eat bugs and grass, and get some exercise every day.
