There is a lot of conjecture with youngsters, I usually let the snake tell me when is right typical 'hunting' behaviour is to lay in wait head out of the hide in the evenings and night Keep an eye on him and if you see this after 3 days try every 5 if you don't see it until 4 or 5 days every week. Typically they are all different, there is no reason to keep them on a ridged timetable if you go every 7 day or so and every now and again sneak one in sooner it is fine.
they seem to grow before your eyes sometimes especially when they are small!!
