Hi there. I have a male Pekin who has some changes to his bill. I noticed it because I was investigating a scratch on the top of his head and took a close look at him all over! The scratch, I believe, is from trying to squeeze out the door when our other duck was making his way out and he likely scraped his head on the top of the door. I'm surprised this hasn't happened before they way the rush out together. At least I'm HOPING that's the case and it's not something his "brother" decided to do to him. Can you take a look at his bill and let me know what you think? It's only on the one side. Since winter has arrived, they've both slowed way down eating and like to spend more time in their house. This is my first winter with them and I assumed this was normal because they are sociable and seem to be in good spirits! But in light of the changing bill, is this a sign of trouble?
