I had one like this last time.Just leave him be. He might look half dead right now, but he isnt. Let him chill for a while, he will get his second wind. All that stuff hanging is normal give him time to soak it up.Dont remove it. Hopefully he wasnt taken outta the shell too early.If you ever end up having to help,do as little as possible and I always leave them in the shell,at least the rear end part of them because theres all kinds of scary stuff happening at that end. Every time you incubate, you learn something new and get better every time too. Im still learning not to worry more than I already have to. Im sure he will do fine. Its a learning process for everyone, even really experienced hatchers.Good luck on the other 2.Keep us updated.
