The Easter Egger is not really a breed. They are relationed to the breeds Ameraucanas and Araucanas, then bred with many different breeds so they no longer fit either breed's standards. They usually have muffs & pea combs, but come in nearly every variety and color, some even have ear tufts or are rumpless. Each EE is different, but overall they are usually a smaller bird that lays pink, green, or blue eggs. They are normally friendly and calm, and their colorful eggs make them a popular choice in backyard flocks.
They are just pretty much mixed breeds that lay colored eggs
