Hi I had a chick with a crooked beak, it started of not bad but it did get worse. She kept eating though and that's all that mattered to me. She had a nice life with yhe flock and got along fine. However this winter she died unexpectedly. We think it was the cold and she wasn't getting as much food as she needed. I don't regret keeping her though. She was very sweet and if I got another crooked beak. I would do it all over again. I hope yours turns out okay
