I have a Beautiful white crested female duck with blueish eyes ,and a Handsome Mallard drake both 5 months. I bought them from Tractor Supply and they got them in free runs. So i had no idea what the sex was and I had to buy two because of store policy or i would have only bought one. I know that crested ducks are born with a hole in their skull and its covered with fatty tissue which forms the poof of feathers on top of their head. Unfortunately i had no idea about crested ducks until i got her, and i had recently been told that if my ducks do mate and my mallard pulls on her crest she can die. Is that true? and is their any way i can prevent them from matting. i DO NOT want to get rid of one because they are both my babies and their both so sweet and have great personalities, so thats out the question.
