Need Help With Crested

[xXNOAHXx]

Okay so i'm a little worried about my cresty, chuck. I don't really know a word for it besides spoiled. He doesn't hunt or feed on his own I literally have to hold the cgd up to his face so he can lick it up. The real reason i'm worried is because his hip bones are showing dehydration. Well anyone would say... give him water? but no he doesn't even lick up drops on his own! Usually i spray it on his nose and he licks it off but I don't like doing this at all because it cant be good if it gets in his nostrils. But now he just wont drink. I've tried before to put the cgd in his cage and let him get it on his own but he just sits there nearly starving and the cgd dries up, and I can't watch my little buddy starve. I'm just really worried if anyone could help that would be great.
