i have two painted turtles. one is a year old and the other is about 5 months. the older on is about 3 times the size of the younger one. the small one's shell doesnt look the greatest, there are like spots on its shell and the belly is rough. well the big turtle is always chasing the little one around and bits it on the neck. it always bits the same spot and bits very hard. the turtles neck has skin ripped off and it looks bad. i was wondering why the turtle attacks the little one. is it trying to kill him or what?
