some bars of comb left over from the winter. I have side wall entrances (like Phil Chandler's design) and on one end they are starting to draw new comb but on the other end they are leaving alone three bars of empty comb. Not going near these and these are not really that old. Why is this????

I'm thinking of removing them and using them to fill with syrup later if I need to feed. I don't know what to think of this since this is my second season. Ideas?
