Griphox's are extremely small when hatched, about the size of a baby kitten,
when they are adult they can get up to the size of a English Mastiff.
It takes Griphox egg 4-6 weeks to hatch
They need to be watched very closely once hatched as it takes them less then an hour to learn how to walk and open their eyes and once they figure that out they will try to explore everywhere, as they get older they get bigger/taller, when they're around 5-9 they'll start to try and fly, of course they can learn to fly at an earlier age but you'll have to help them, you'll still have to help them to fly anyways but they'll need more help. They love collection anything that shines, even trash so if you throw a shiny piece of trash make sure your Griphox doesn't see or they will dig threw the trash to find it, and if they find it do NOT try and take it away, just clean the trash and let them have it, even if it's sharp, they are smart creatures so they know when something is dangerous. During their teen years they can be rebellious sometimes but don't lose your patients and get mad at them, simply tell them "if you want to do whatever you want, the door is that way" and point to the door, that will show them you won't stop them from leaving, they are proud creatures so they will leave, but give them a few hours and they'll be back, after realizing they have no other place to go, and that they miss you. When they're adults they'll spend as much time with you as possible, do NOT push them away when they do so. They're very loyal and protective so they will do almost anything you say as an adult Griphox, and they'll protect you from any type of danger.
