I finally got up to the Island for the day today to inspect and feed the hives. I dug into them and unfortunately only three made it through the winter - none of the swarms from last summer survived. It looks like the cold got to them - some honey stores remaining, no signs of disease, and the bees were head-in to the comb.
But the remaining hives look healthy and in good shape! Planning to split the most robust hive (the one on the right in this picture) - need to order a queen for the split.
