Hello all. I am a new Beek living in very rural WV. Trying to do this with/by the book. So far pretty good I think. I have Carnies, 2 hives, and have already added the 2nd super. My question is, when to add the third ? Checked the hives this morning and one has all of the second hive made into combs but not filled. Do I go ahead at this time and add the queen excluder and super or do I let the frames start filling ?
