I checked the hive yesterday afternoon and early this morning, and about every 10 seconds a worker bee would return with full of orange or white pollen. Occasionally I was seeing some yellow as well. This weekend I’ll open up the hive and check to see if they have started to fill out the three new frames I put in on Wed. Since it has small cell wax foundation in it, I’m hoping they’ll get right to it. If those frames are being worked on, I’ll add on a medium super on top with wax foundation as well. Gotta give them room for expansion this summer.
