I only had enough time to inspect Yellow and Green. Purple over-wintered with 4 boxes, Green had 3 and Yellow had 2 and a feeder. I figured Purple was the lowest priority because they probably had enough space to start taking in nectar for a few more weeks.
When I opened up the Yellow hive, they were definitely running out of space. In this picture the bees are building burr comb through the inner cover of the Yellow hive:
Other than that, Yellow seemed to be doing ok for laying space, so I threw an empty super on top, making Yellow 3 boxes high. Almost every single time I have opened Yellow, I have seen the queen. Here she is again:
Green hive was also running out of space and had a ton of burr comb everywhere. It looked like they had no space to lay eggs, so I threw on an empty super below the top-most super, making Green 4 boxes high. Here is the burr comb in the Green hive:
The Green hive also seemed to have a lot of pests on the bottom board. Hopefully they are doing ok. I did notice some curled up wings in the Yellow hive - that is a sign that they have a high mite load. Here is the bottom board of Green, you can see a hive beetle and many mites (the little red circles) amongst the wax crumbs.
