All griffins go through several stages before they are fully mature. The amount of time it takes for a griffin to grow up varies, but is around five days and never more than a week.
ChicksEditAll chicks are the same color as their eyes when they mature (oilspill eye color is sometimes called "dark brown" but still matches the black chick). Rainbow griffins are always the same color as their eyes and eggs, but you still will not know the shade at this stage.
Owners should pay a lot of attention to the cub stage. Sometimes it will tell you things the adult look doesn't!
Each shade has a corresponding cub color. This is important in predicting rainbow looks, because they do not show shade in the egg stage.
Pattern can be determined by the phenotype symbol on the griffin's pedigree. Cubs who will have patterns have white spots at this stage.
Griffins with fairbelly will first show it at this stage.
Cubs with the black gene have darker wing tips. White and rainbow griffins don't always show the black gene as adults, so the cub stage is a great way to tell if your griffin has it.
