From the Easter Eggers I have raised, these are the pros and cons that I have seen/know of
Pros:
-lay beautiful pretty colored eggs
-each is unique and come in any color
-all the different colors they come in makes it easy to tell them apart
-peacombs make them winter hardy
-very kind birds
-only one of mine went broody once (this could be a pro or con depending on if you want chicks or not)
-you never really know what they'll look like as they get older
-from what I've heard, the roosters are generally docile, mine was
-seems to be fine with confinement or free ranging
-the babies look like chipmunks!!
Cons:
-usually slow to mature
-flighty
-don't do do well in very hot climates
-not extremely consistant layers. I have 5 laying right now and get anywhere from 0-5 each day. I can't really predict how many I will get.
-aren't a recognized breed so they can't be shown
