So this is the first time I've ever had ducks. I ordered one runner and one white crested. They are both totally cute, cuddly and completely hilarious. However...Ping, my white crested, has a bit of a "hair" problem. The crest is totally loop-sided and even tends to tilt his/her head to the side. Can I or even should I trim it so it's more even? "I totally ROCK!"
