Steve checked the hives on the 30th June, the station feeders needed cleaning out as the ambrosia had solidified.  He was unable to inspect the comb, which he could see they are begining to build, because he didn't had a spray to send the bees back into the hive when replacing the tops bars and didn't want to squish any bees.  The bees are moving in and out of the hives, although the smaller colony is less active.
