I now know the crest is a skull deformity. After finding out details I was never going to allow them to hatch their own eggs. But I have 1 black crested and 3 whites. Plus a white Pekin drake. All the white ducks are racist! So I was going to get Ebony some black companions, aka the Cayugas. But now, Howard the drake is on thin ice, he tried to drown Ebony yesterday and has been chasing her off food. If he continues this behavior he either gets rehomed or becomes dinner! Crazy duck.
Uuuuuuummmmmmmmmmm...Howard's in truuuuuuuuuuuuuuuuuuble!

Sounds like your typical teenage boy.
