To me your retic looks mighty thin. My dwarf retic can eat up to 10% of her body weight every five days! I'd feed way more until you get some girth on that snake, then once they fill out a bit you can cut way back. My dwarf just passed the ten pound mark and is now too heavy for my scale LOL. When they are young their metabolism is super fast, in just two days a large rat bump is completely gone, personally I think they should be fed every five days when young. Once they get a bit bigger and older they slow way down.
