A Badly kinked normal that you have to force feed with a tube?

Sorry, but especially after seeing that picture, I would have to disagree with not euthanizeing it. It's not like it is a insignificant little kink on the tail.... that is a major kink in the middle of the snakes back... In the middle of his digestive system.

How exactly will you measure if it can successfully live? If it finally at some points eats by itself? How do you know it is not uncomfortable or in pain all the time? Refusing to eat as a hatchling when its siblings are all eating just fine is a good indication of this I would think.

But, it is your snake and you can do as you want. Not trying to hijack your thread so I will no comment any more.
