I don't think this is a huge problem because my duckling hasn't had a crooked neck exactly, but the fat lumpy right under the neck in front of him appears crooked. He's eight days old on unmedicated starter, with constant access to water and food. Today my mum noticed the fat lump seems crooked but it's our first time having a duck. I actually don't know if it stores fat.... But that's how I've been designating it. Lol. I don't necessary think it's a huge problem because he runs around, eats, drinks, but you can tell one side is more rounded and it storing more. I'd rather be safe than sorry, but this is a new development in his.... Development. Thanks in advance, guys!
