Re: Should I feed new bee's in summer?
I'd feed them until a week or so before you plan to add honey supers. They will move syrup around in the hive and its best if they don't move it to the honey super. Keep an eye on them filling the brood cells with sugar syrup and stop feeding if they filling the brood area cells with syrup.
You need to do some manipulation to get the hive to expand the five frames. Keep two drawn/brood frames together and then insert an undrawn frame. Then place two more drawn/brood frames and insert a second undrawn frame. Spray the undrwan frames with sugar syrup. Keep doing this periodically until the first brood super is 80% drawn frames.
Then move brood frames to second brood super when you add it and intersperse an undrawn frame between pairs of drawn/brood frames.
