alright soo i happen to think crested ducks are soo adorable, and have been thinking about ordering some hatching eggs from some crested ducks, but here my question, are crested ducks harder to hatch out? and do they tend to have more health problems or neurological problems or fatalities or anything like that? also, what actually IS the crest? is it just a tuft of feathers, or is it like a growth from out of the head thats covered in feathers?
