Last Sunday, (4 days ago), I installed a 4 lb. package of Russians into an 11 (reduced) frame medium, with drawn 5.1 comb and a hive top feeder. Today I noticed quite a lot of bees hanging out on the underside of the inner cover and trying to draw comb there, hanging down into the feeder. I'm wondering if they should have a second hive body this soon after installation, or is this just normal behavior. (I usually use 3 lb packages). Queen is laying, but seems like they're using the frames more for honey storage than for egg laying.
Thanks for any responses.
