Many hens lay white eggs. I have a black wyandotte (

and she lays white eggs. Years ago, someone decided that brown eggs looked more appetising and all commercial hens were bred to produce brown eggs. The white eggs taste just the same as the brown eggs from my ex-bats. Generally, if a hen has white earlobes it lays white eggs. There is even a hen, Araucana, which lays blue eggs.
