They all really do have different personalities. My adult male is pretty easygoing, loves to eat treats out of our hands and doesn't run and hide, but he is TERRIFIED of the color red. He refuses to eat anything red, even rose petals or hibiscus, and if we walk into the room wearing any red clothing, he runs and hides. He also freaks if we try to hold him, even though he's not afraid of our hands at all.
Our two baby saharans are very different from eachother. Nothing phases Pooka, she ate our of our hands from the first day and always runs over to our hand to lick and explore any time we clean, put in food, etc. Baby Chili, on the other hand, is just now getting to where she won't run and hide every time we walk into the room, and we've had her for about three months. Their personalities are so different.
